Heat Map: World Acceptance Towards Homosexual

Last year we have shared several maps about homosexual, and we have also created an interactive heat map for showcasing world acceptance towards homosexual. Today, we have found another heat maps for more information.

Here is a heat map, which was created by Pew Research Center after interviewing around 38000 interviewees from 39 countries from March to May last year, showing which countries accept homosexuality while which do not. In the map, the darker red represents lower acceptance while the greener represents higher acceptance.

This heat map is similar to our interactive heat map that created in last June that countries like Canada, Australia, and Argentina.


Map Reviews: 3/5 Stars
The map cannot display the whole picture of the world acceptance towards homosexual as only little amount of people from 39 countries have participated in the research, and people from many countries, like India, have not been interviewed.
There is also a minor suggestion towards the above heat map that heat map legend is needed for indicating the heat map colors.

In Flight, Tracks All the Planes in the Sky

We have experienced being trapped in the airport because of the flight delay or cancellation. Today, The Guardian launched an interactive live map for showing all the planes currently (or flights within 24 hours) in the sky across the globe that passengers can now track the flights.


Map Reviews: 3.5/5 Stars
It is an interesting and stunning interactive map for seeing all the planes are currently flying in the sky. However, the loading of the map is not that smooth due to the large data source. Furthermore, you cannot use this map for tracking your delayed flight as it is not an informative tool map.

Heat Map: Map shows Countries Are Responsible to Climate Change

If you are wondering which countries emit more carbon dioxide and should be more responsible to climate change, you may refer to the following heat map for more ideas.

This heat map is created by New Scientist that the size of each countries are based on the amount of greenhouse gases they emit.


There are 0.74 °C warming between 1906 and 2005, and the United States is responsible for 22 percent (0.15 °C ) while China and Russia are responsible for 9 percent and 8 percent respectively.

It is interesting that though the U.S.A., China and Russia are countries should be most responsible to the climate change, United Kingdom and Germany are countries mostly heated.

We all understand that global warming and climate change is a world-wide issue that we all should cooperate together, and tackle it. For more information, you can refer to:

Sightsmap, Photographed Locations in the World


We are all familiar with Google’s Street View, but if you are interested in the world’s most photographed or most checked-in location, you may have to look for the Google’s Sightsmap.


Sightsmap is displayed in heat map version as default that map users can find the most photographed area in yellow color, and more makers will be displayed by zooming into the region. Photo, streetview, external link to Wikipedia or other webpages will be displayed in the popup box by clicking the marker, that the data is mainly obtained from Panoramio, Wikipedia, and foursquare.

Map Reviews: 4/5 Stars
This map is just another version of “Street View” that let us explore the world by just leisurely sitting in our room, and the main differences of this Sightsmap with Street View are the images were taken by other people, and much more beautiful, for example you can see the sun set in Paris and the night view of Cologne in Germany at the same time, which Street View cannot satisfy us.

This map is wonderful with thousands images, so at the same time, it may take longer time for loading the heat map. Furthermore, markers in various colors are pinned on the map that map legend is needed for indicating the colors. (Markers in lighter colors represent higher popularity.)

Map users can also user the “trip plan” menu to get help while planning a trip using this map. We found this feature is very useful when you are planning a trip without any prior idea. You can:

  1. Select a starting point on the map
  2. Select spots for visiting
    (Or you can select “recommend” that suggested by the system)
  3.  Click “Show” to see the “Trip itinerary” for details (e.g. travelling time between spots, estimated visiting time in the spot, external links for the spot)
  4. Click “clear” to reset

Overall, this map is informative and useful for planning the trips by providing estimated visiting time, photos, and useful links. Let’s check out the map HERE.

Interactive Health Map, Tracks All Diseases Across the World


HealthMap is a real-time interactive world map for displaying all diseases across the globe that it was founded by Boston Children’s Hospital in 2006.

HealthMap obtains data from various sources, e.g. online news, witness reports, expert-curated discussions, and validated official reports, to maintain the map as comprehensive as it can.

There is also a mobile app for this map, “Outbreaks Near Me“, that deliver real-time information on a broad range of emerging infectious diseases.

Map Reviews: 4.5/5 Stars
First of all, the map is informative and useful enough for us to better understand the outbreak of diseases around us and even across the globe. There are many category legends (i.e. type of diseases, locations, sources, species, dates) for filtering that users can better search specific information in a shorter time.

There are other additional features to make the map user-friendly enough to keep us returning to this map. For example, search result can be displayed in list view with filter, and can be displayed in chart for showing the trend.

We love the simple design of the map as well that it uses clustering to keep the map as neat as it can. Map legend and map labels are hidden as default but users can enable it when necessary.

This map also supports English, Spanish, French, Portuguese, Russian, Chinese, and Arabic that I believe more languages will be launched in the coming future.

Last but not the least, map users can also provide source and information to the map by clicking the “add alerts” button on the top right corner of the map that make the map more informative and comprehensive.

World Map of Social Networks

Facebook is always the most popular social network platform across the world, even there is rising popularity of Instagram. Here is a world map that showcasing the most popular social networking sites by county in Dec 2013. The map is created using Alextraffic data and is updated every 6 months.
world-map-of-social-networks-2013According to the map, Facebook has already become the most popular social network platform across the world, except those countries that has closed the door for Facebook (e.g. China).

Currently, there are 1189 billion active users in Facebook per month, though the growing rate is comparatively lower than before, that there are 351 million users in Asia, 276 million users in Europe, 199 million users in US & Canada, and 362 million users in other countries.

It is quite surprising that there are more active users in Asia rather than in US, the origin of Facebook.

In Russia, V Kontakte and Odnoklassniki are still competing to conquer the leader place in the market, and currently V Kontakte is placing the position.

In China, QZone still dominates the Asian market with 623 million users, however, it’s growth is being slowed down by the rising popularity of Weixin recently.

Here is another image shows the changing of popular social networks across the world since June 2009.

Heat Map: How the World Think Towards America


How do you think about America? The Pew Research Global Attitude Project has tracked opinion in 39 countries to see how the public think about the United States, and then Business Insider, Australia rendered the data in the below heat map.


According to the map:

  • Philippines, Ghana, and Israel even have higher opinion of the U.S. rather than Americans.
  • Among all the Asian countries, South Koreans have the highest opinion towards the U.S.
  • People in Pakistan are most unfavorable towards the U.S. among all the interviewed countries.

Detailed bar chart report can be seen HERE.

The static world map and bar chart can be combined into an interactive map in few steps:

  1. Create heat map by importing heat map data
  2. Create mouseover infobox for each region
  3. Insert bar chart image into each infobox
  4. External links can also be added to the regions for additional information

World Map: Gay Marriage in the World

In the past, we have shared several maps about same sex marriage in the United States and world acceptance towards homosexual, and now we have found several maps about the same sex marriage around the world in different countries.

the-gay-marriage-world-mapmap legend for the above world map:gay-marriage-world-map-legend

Since the first legal same sex marriage took place in Amsterdam in 2001, there have been 15 countries (e.g. certain states in US, part of Mexico, Australian Capital territories) legalized it within these 12 years. However, there are still some countries do not accept homosexual (e.g. Sudan, Saudi Arabia, Yemen).

According to below image, it seems that homosexual is more acceptable in Europe that most of the European countries allow same sex marriage, and  same sex unions are allowed.

This gay marriage map can be converted into multilevel interactive map that detailed information can be added to each countries with popup infobox, and map legend can be created for indicating various region colors.

Here is a video tutorial about creating multi-level maps:

Interactive World Map: Where are the Next Silicon Valleys

Once there is a new innovative startup hub, journalists would label the area as “the next Silicon Valley”. Since there are various “the next Silicon Valleys” across the globe, Slate has then created an interactive world map for pinpointing all the locations for presenting a whole picture for our better understanding.

There is a list of editorial pieces along  the map that users can select an article on the list to see the highlighted pin on the map and link to the full text by clicking the inserted URL.

According to the map, we can see the new hubs are named as Silicon Alley, Silicon Hills, Silicon Forest, Silicon Prairie, Silicon Square, Silicon Wadi, etc. Do you think these nicknames can really make the region to be the next Silicon Valleys?

SickWeather Maps

Nowadays we are more awareness about the spread of infectious disease but we have no idea about how to avoid being inflected in the public area. Here is an interactive map app for presenting areas with sickness report. Since people are used to post feeds on social media sites like Facebook and Twitter, this map gets data from these platforms (if the users make the information public with location information). Furthermore, members of SickWeather can directly report their status to the map. After gaining data, the map will generate polygons of sick zones that remind users to avoid. SickWeather is available as both a website and as a free iOS mobile app.


Map Reviews: 3.5/5 Stars
We love this idea which is useful for tracking potential infectious disease zones, but some improvements are needed to make the map become more user-friendly.

  • Bigger map legend as the current map legend is too small to read the legend items.
  • It would be better if there is mouse click infobox for each polygon and infobox for each symptom report.
  • Can categorize illnesses using various polygon colors.

Data for this map is not complete since people in several countries cannot access to Facebook and Twitter (e.g. China, North Korea), and not many people will really contribute the information online. But anyway, this map is a good fresh idea that we are looking forward to its later development.
