Today I cleaned up the same dataset I used for the previous blog entry and created a new map. The following map, I believe, better reflects geographical distribution of New York city residents on government subsidies. First, unlike the previous map where you can see place markers ironically misplaced in Europe and elsewhere, this improved map has corrected the error. All place markers are now located in New York city and its surrounding areas. Second, each place marker has an accompanying number that indicates how many people in that area are receiving public assistance. Third, I changed the colors of the place markers. The darker the color, the greater number of poor people in certain areas. This is definitely more intuitive than the one I posted before. Lastly, I changed the map from map view to satellite view to see if it looks better.
Currently, WordPress.com doesn’t allow its bloggers to embed a map created with Google Fusion Tables. This is because “www.google.com/fusiontables” is not yet on the whitelist for embedding maps. So I created a hyperlink for the map. Click here and you will be able to view the map.
Fortunately, WordPress.com works with Google Maps because Google Maps is on the whitelist for embedding. You will be able to view the map without clicking a hyperlink. Below is the map I created with Google Maps.
The map I customized shows where and when different species of caterpillars and butterflies were found in Central America. Different colors of the place markers indicate different years. Here is the source of the data.
