{"version":"1.0","type":"rich","title":"CS360 A10","description":"A choropleth map of the United States visualizes the average monthly transportation cost by state, with a color scale from light yellow to dark red. The map is rendered using SVG paths projected with `d3.geoAlbersUsa` and `d3.geoPath`, with state boundaries drawn as black strokes. Fill colors are assigned based on the `transportationCost` field from the `StateExp.csv` dataset, mapped through a linear color scale. A horizontal `d3.legendColor` legend displays the cost range, and a hover interaction logs the corresponding state ID to the console.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af2c910aa09244ae8dc4f639554686fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
