{"version":"1.0","type":"rich","title":"A5 Bubble Chart D3","description":"This bubble chart visualizes police shootings by age and race, with each circle representing the count of incidents for a specific age and racial category. The x-axis maps age, the y-axis maps the count of shootings, and circle size encodes frequency using a square-root scale so area remains proportional. The chart is built with D3 v7, loading CSV data, aggregating with `d3.rollup`, and rendering SVG circles using scales like `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` with `schemeCategory10` colors. Axes and labels are added via `axisBottom` and `axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3eaff508ca8243dbbe1722e849e97dc1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
