Heat Map: Arsenic Risk in China’s Groundwater

Researchers have developed a new statistical model to estimate the risk of arsenic contamination in China’s groundwater, and a heat map has been created based on the research result.


Based on geological, soil, and topological data, a statistical risk model was created by researchers from China and Switzerland to identify high risk areas for groundwater quality monitoring.

Circular Rail Maps for Sydney and Melbourne

A London designer, Maxwell Roberts, has prepared schematic maps for rail systems in Sydney and Melbourne based on the geometry of concentric circles.



Maxwell Roberts is a London psychologist who has created a series of circular schematics of transit systems in various cities, including London, New York, Berlin, and Tokyo. Maxwell was surprised the amount of cities can be fitted to the design rules and the results are often spectacular from an aesthetic point of view.

We have introduced a London tube map with attractions before that we can find that tube / transit system maps can be used in various way with different designs. You may now utilizing your city’s transit system maps (e.g. metro maps, bus maps, train maps) to create your personalized maps for particular use.

Global Flood Damage by 2050











Issues about climate changes, e.g. global warming & rising sea level, are always hot topics among us in these years. A world map about damages caused by flooding and rising sea level by 2050 has been created for warning us.

In the bubble chart map, it highlight several coastal cities about the estimate cost that taxpayers have to pay for cleaning up the casualties caused by flooding. This map is created based on the analysis from Stephane Hallegatte, an economist in World Bank, and his coauthors, and he mentioned that the figure was just the bare minimum. Detailed comment from Stephane can be found by clicking the above map image.

Recently, we have received inquiries about creating world map with pie chart / bubble chart per country. It is possible to create bubble chart in a world map using map maker for data analysis:
