SVG has an opposite y-coordinate system (0 is on top, height() is at the bottom). stroke, fill, clipping, etc. My goal was to create a dynamic graph that I could add, edit and remove data and have d3 update the graph in real time but I couldn't understand how to handle enter() and exit() with JSON. Responsive Charts with D3. A confession: I'm starting to hate choropleth maps.
When it comes to comes to comparing U.S. states, especially where there's no obvious geographic pattern, a map is often the wrong choice.
