{"version":"1.0","type":"rich","title":"Section 1(a)-Making Maps Using TOPOJSON","description":"This choropleth map visualizes 2024 US state unemployment rates using D3.js v7 and TopoJSON. It shows each state colored on a red-yellow-green sequential scale, where green indicates lower unemployment and red indicates higher rates, with hover interactions revealing exact percentages via a tooltip. The map uses `d3.geoAlbersUsa` projection and `d3.geoPath` to render state boundaries from the us-atlas TopoJSON dataset, while `d3.scaleSequential` with `d3.interpolateRdYlGn` drives the color encoding, and an SVG linear gradient legend communicates the scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58f3642868b746f78fdb3c234e6be237?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
