Recently, we found a U.S. heat map related to the minimum wage laws for showing how much hours we have to work for affording rent on minimum wage.

us heat map number of hours at minimum wage needed to afford rent

According to the newly released report from the National Low Income Housing Coalition, minimum-wage employees have to work on average 2.6 full-time jobs to afford a decent two bedroom apartment in the USA without paying more than 30% of their income.

However, people in Hawaii (174 hours), Maryland (138 hours), and Washing D.C. (137 hours) have to work for more hours in order to afford the rent when compare to other states, even the states have a higher minimum wage than the federal minimum wage.

The above two maps show higher minimum wage doesn’t translate into housing affordability.

How to create similar heat map for presentation use?
It is very common that we create heat map for statics report with some map features (e.g . popup boxes, group highlight, map legend, labels). By utilizing some mapping software, we could easily import data file and create the maps with few clicks. Here is a video tutorial of creating heat map & bubble chart.

You could select for specific year by moving the timeline on the top right corner. For those unlabeled bubble, you could refer to the map legend for indication.

Chart features suggestions:
We could integrate this bubble chart with a world map for better present the data changes as map users can quickly recognize the country on the map if there is no region abbreviation or map legend for indication. Furthermore, since the positions of the bubbles would change by year, it is a bit hard for the map users to instantly compare the changes.
When integrating the bubble chart with the world map, size of the bubbles would still indicates the amount of stared restaurants, just like the current one.

Here is a video tutorial of integrating bubble chart with map without coding:

Interactive Google Maps Shows Locations of all the US Shale Oil and Gas Wells

Rating:

Post Carbon Institute has created an interactive Google Maps that shows over 63,000 locations of the U.S. shale gas and shale oil (tight oil) wells, using data from Drilling Info.

Regions for different plays (i.e. shale oil plays, shale gas plays, oil and gas plays) are highlighted in various colors on the map, however, there in no mouseover infobox for these regions. Details for individual plays (e.g. production date, well ID, gas production status) can be seen by mouse hovering the red points.

Presenting detailed information is always the main purpose of informative map, however, this Google Maps got a mistake in infobox design causes the low rating in our map reviews. The size and the position of infobox are fixed that there will be a scroll bar when the text content a bit longer for several points. However, the infobox is a mouseover event that the popup box would disappear once the mouse hovering off the point. So, how can the map users see the full infobox content by scrolling the scroll bar? The issue can be easily tackled by changing the event to mouse click box or re-size the infobox.

Interesting Heat Map Shows How Popular Your Name Is Across the United States Over the Past Century

We just found an interesting heat map that you could check the popularity of your (or your family and friend’s) name(s) across the U.S. in the past 100 years. Simply enter your name in the search box, select the gender, and then wait for the GIF heat map tells you the answer. interactive us heat map popular baby names

You could see the heat map about popularity of your name from 1910 to 2012, and detailed statistics can be found in mouseover box of each state.

Map Reviews: 3.5/5 Stars
This map is interesting for us to search how popular our names are in the past century. However, a timeline is omitted that we would not select specific period as the heat map is some kind of a GIF image. As there are so many regions in the heat map, it is impossible for me to mouseover all the boxes within one second for detailed information, therefore, I have to refresh the map and wait for the specific year again. It sounds a bit silly.
This heat map will be better if a timeline or a pause button is enabled.

We like this map, includes the map theme, the usages, the map color settings, and present of the marker list. However, it would be better if there is clustering feature, and improved performance for the filtering function.

Since there are over 600 points on the map, it would be better present those points with clustering, which is a way to group markers on the map based on factors, such as proximity or map data that makes the map leaner and cleaner without flooding with overlapping markers. You can get more idea about clustering in the following video:

Map: US Gender Pay Gap

We all know that there is gender pay gap that women get less salary than men on average, and we have shared an interactive Google Maps about this phenomenon in New Jersey before. Here we have found another U.S. for showing a wider picture of this issue.

heat map us gender pay gap

According to the above chart and map, we can see that women make 77 cents for every $1 earned by men in average, and women in Washington, D.C., Marland, Nevada, and Vermont can even earn more than 84 cents for every $1 the men make. However, the gender pay gap still exists, that happens in every county, and even female employees working in the White House make less dollar than men.

So you think the gender pay gap is an issue that has to be solved? Share your views with us.

This heat map is not user friendly to read as the color setting is a bit complicated. We would suggest using continuous color rather than the current discrete range color since the former can better present the differences of data values in various counties.

Interactive Heat Map: Global Slavery Index 2013

According to the Walk Free Foundation’s Global Dlacery Index 2013, there are nearly 30 million slaves in the world, and almost 60,000 of them are living in the U.S. Here is an interactive world map about the index.

According to the Walk Free, slavery defines as one of the following: human trafficking, forced labor, debt bondage, forced or servile marriage, and the sale or exploitation of children including in armed conflict.

The index ranks 162 countries based on a combined measure of three factors: estimated prevalence of modern slavery by population, a measure of child marriage, and a measure of human trafficking in and out of a country.

The index is mapped into two maps: an interactive heat map & an interactive bubble chart. In the heat map, country with higher slavery prevalence is highlighted with darker red while country with lower slavery prevalence is highlighted with yellow. Map users could see details of each country by mouse clicking the region, or select specific category in the category legends.

In the bubble chart, countries are being plotted on the chart according to their prevalence rank vs human development index/financial service index/corruption index. However, there is no popup box of each bubble for detailed information, and no map legend to indicate various bubble sizes that a bit confuse the map users.

interactive heat map the global slavery index 2013

According to the index, 10 countries with the highest prevalence of slavery are Mauritania, Haiti, Pakistan, India, Nepal, Moldova, Benin, Cote d’Ivoire, Gambia, Gabon. Among all the above mentioned countries, India has the most slaves in the world, with an approximated 14 million. 

However, even countries like Iceland, Ireland, and the United Kingdom rank 160 in the index, it does not mean these countries are slavery free, for example, it is estimated there are between 4200 to 4600 “slaves” in the UK.

Map Review: 4.5/5 Stars
We love this map as the map design is simple but informative with clear instruction and indications for users to filter related information in seconds.
There are just minor suggestions to the bubble chart:

  • add a map legend to indicate the bubble sizes
  • insert infobox for each bubble for detailed information

Alternatively, showing data of each country with bubble can be presented on the world map rather than on the chart. Bubble chart map can be easily created in mapping software that you may take following video for reference:

You cannot see how “interactive” this map is until you zoom in to each point and mouse click for the details. In the popup box, you have to mouse click the inserted URL in order to read detailed information in the information column that on the right side of the map. This process is a bit unnecessary as popup infobox with detailed information can be directly shown once the map users mouse click the bubble. Here is a video for reference:

Please note the map supports French currently, and let see if versions in other languages would be released in the future as this map is an informative tool for related research and educational use.

Best Coffee in NYC by Subway Stops

Rating:

We have shared various subway maps, no matter those are interactive or static, all the time since subway maps are so common and important to us in our daily life, especially to those who take subway everyday. Here we have found another useful subway map for busy New Yorkers to check out the best coffee around you by subway stops.

This NYC subway map is created by Butterfruit Labs that shows the best coffeehouses in Manhattan by subway stops. The standards of being “the best coffeehouse” are equipment they used, the type/source of beans, stop proximity, and reviews from both customers and professionals. You may find that Dunkin Donuts & Starbucks maybe in the map since some locations do not have great options other than these two.

Let’s try all the best coffee in town by following the map!

Subway map is the best material to create interactive image for various purposes, e.g. introduce attractions by stop, share audios/videos by stop, or introduce best coffee/restaurants by stop. This map is useful and informative to those living in NYC, especially those coffee-addicts.
Last year, we have shared an interactive Kuala Lumpur map of independent cafes, which provides detailed information for each cafe in pop-up boxes. Similarly, the above subway map can be more informative and interesting by converting it into dynamic images with tooltips/description boxes.
Furthermore, category legends can be created for categorizing those chain stores and independent cafes.
Let’s see if any interactive subway maps will be created in the future for another topics, and please feel free to share your findings to as well!

Interactive US Map: The Most “Pleasant” Days in a Year

Have you ever counted how many pleasant days or sunny days you can enjoy in the U.S. per year? Here is an interactive map that presents the analysed result for your reference, and it is unsurprising that South California is the best state to enjoy pleasant days.

This interactive map is created by Kelly Norton, a designer and software engineer in Atlanta, using data from the National Oceanic and Atmospheric Administration for the past 23 years. According to the criteria of Norton, a “pleasant” day should be:

  • mean temperature between (55° F and 75° F)
  • temperature between 45-85 ° F
  • no significant precipitation or snow depth

us map pleasant days per year

According to the map, the top five pleasant places in America are Los Angeles, San Diego, Oxnard, Simi Valley, and San Francisco, which are all in California that residents there can enjoy over 150 pleasant days per year. Conversely, residents in MC Allister, Northeast of Reno, Clancy, and Douglas can only enjoy around 15 pleasant days per year.

Please note that the criteria of Norton is subjective and based on his own experience. Let’s check out the map and see if you agree with him or not.

Map Reviews: 4/5 Stars
This map presents an interesting survey result on a neat and simple interface that all cities are being represented by circles, and further information with a bar chart can be found in the mouseover box.
The map is user-friendly enough with a search box for searching places using zip code, though it will be better if it also support searching by addresses.
There is also a little suggestion for the map that a key legend can be created for indicating the circles’ colors as darker blue represents city with more pleasant days while lighter blue represents fewer pleasant days.
Overall the map is interesting and quite informative, though not very objective, with nice design. More similar maps can be created using custom images by utilizing some image editors.
