{"version":"1.0","type":"rich","title":"Fork of WAEVData (Fork of Choropleth by bepnye)","description":"This visualization explores the distribution of electric vehicles (EVs) across Washington State counties, linking a choropleth map with a scatter plot of EV count versus real GDP per capita. Circles are sized by population and colored by county type (urban or rural), while the map uses a green gradient to show EV density. Users can hover for details, brush on the scatter plot to zoom, and double-click to reset. The visualization uses D3 v6 with `d3.geoPath`, `d3.scaleLinear`, brush interactions, and tooltips, reading data from a GeoJSON file and CSV source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a8128624d9743aeb137b2684df5b5af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
