Choropleth Map
This choropleth map visualizes countries colored by their economy type, using a spectral color scale with an interactive legend. Built with d3 v5 and the topojson library, it renders natural earth projection paths as SVG elements. The map displays data from the world-atlas package, with country names and economy values shown on hover. A zoom feature allows user interaction, while the legend uses a custom colorLegend component to map ordinal categories to colors.
