{"version":"1.0","type":"rich","title":"A7 Small Multiples Chart D3","description":"This example presents a 2x2 grid of small multiple line charts, visualizing police shooting counts per year across four racial categories. It uses a D3 v7 ordinal color scale and time scale, with data loaded from a CSV file. Labels and legends are added with d3-legend. The code uses `d3.csv`, `d3.group`, `d3.rollup`, `d3.scaleTime`, and `d3.line` to construct shared axes, create the line generator, and arrange chart groups via manual translation transforms.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7479ae2a76c34972b55785a831437531?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
