{"version":"1.0","type":"rich","title":"Unemployment Rate Heatmap","description":"This interactive heatmap shows monthly unemployment rates for selected U.S. states, with darker blue cells indicating higher rates and a vertical legend mapping the discrete color thresholds. Hovering over any cell reveals a tooltip with the state, month, and exact unemployment percentage. The visualization is built using d3.scaleBand for the axes, d3.scaleThreshold for the color encoding, and SVG rectangles rendered with D3. Data comes from the \"Unemployment in America Per US State\" GitHub dataset, with states sorted by descending unemployment rate.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/347dee7845ba4490a2826b587ba3af08?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
