This interactive visualization displays a choropleth map of the United States showing the geographic distribution of petition signatures, with each state colored on a logarithmic scale—darker shades indicating higher signature counts. Built with D3 v3, the map renders as an SVG using a linear color interpolator as a stand-in for a true logarithmic scale, since the data spans from dozens to over 4,500 signatures per state. Users can click any state to see its exact signature count. The visualization also includes a pie chart view of the same data and was originally created as part of a bioinformatics group project, adapted from Mike Bostock's map demo.
AI-generated descriptionhttps://gist.github.com/4544529 (demo) was my first d3 adventure, where I scraped signatures from a White House petition and showed them as a pie chart.
Here, I show them as a US heat map (based on one of Mike Bostock's map demos). You can click on a state, and see how many signatures came from it.
Darker color means more signatures, but since the numbers range from a few dozens to >4500, the scale is logarithmic.
I don't know yet how to use log() interpolators (I promise to learn), so I just did it quick and dirty with linear() and masking tape.
