{"version":"1.0","type":"rich","title":"Heatmap with time series in D3","description":"A heatmap displays annual property-crime rates for U.S. states from 2000 to 2019, using color intensity to show per-100,000-person offense counts. It uses `d3.scaleThreshold` with `d3.interpolateBlues` to map rates to colors and a sequential color scale for fill, while `d3.legendColor` provides a threshold legend. Data comes from the CORGIS smoking dataset, filtered for property crimes. Tooltips reveal exact values on hover, and axes are labeled using `d3.axisBottom` and `d3.axisLeft`, with the SVG rendered via D3 v6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/13555e0689b04ca7968b57e910a9db4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
