{"version":"1.0","type":"rich","title":"A6 Scatter Plot","description":"This scatter plot visualizes the U.S. police shootings dataset, showing the count of shootings aggregated by victim age and race. The code uses D3 v5’s `d3.nest()` and `rollup` to group data, then plots aggregated circles with `d3.scaleLinear` for axes and `d3.scaleOrdinal` with the category10 scheme for race colors. Axes are labeled with `d3.axisBottom` and `d3.axisLeft`, and a color legend is rendered via the d3-legend library. A linked YouTube tutorial explains the implementation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4797aa2391a84c5581d673aff8e84877?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
