{"version":"1.0","type":"rich","title":"Line Chart Using a Qualitative Color Scale with D3","description":"This line chart tracks abortion rates over time across multiple U.S. states, with each state represented by a separate colored line using a qualitative Set1 color scale from ColorBrewer. A legend to the right identifies each state, and hovering over individual data points reveals an interactive tooltip with the year, state, and rate. The visualization is built with D3 v7, using `d3.scaleOrdinal` for color assignment, `d3.line` for path generation, and SVG rendering with animated tooltip transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c33575c0478945d38f7d87e38ff04f56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
