d3 choropleth map
✓ Published0🌍 Public
This example displays a choropleth map of world countries using an Eckert5 projection, with colors representing numeric data values for each country across multiple years. A play button animates through yearly data from the CSV file, updating the map and a clock display to show the current year. The visualization uses d3.v3 with geo projection and path APIs, queue.js for loading the TopoJSON geometry and CSV data, and renders all elements as SVG. The code includes a graticule layer and country boundaries for geographic context.
