{"version":"1.0","type":"rich","title":"Heatmap with D3","description":"This heatmap visualizes abortion rates per 1,000 women aged 15–17 across U.S. states over multiple years, using a linear color scale from light gray to red to indicate rate intensity. The D3 v7 code loads data from a CSV and renders an SVG with `d3.scaleBand` for the x- and y-axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.scaleLinear` for color encoding. It appends rectangles for each state-year pair, plus a legend and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3fa1e907ca904d43bc0eee0ec038e5c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
