{"version":"1.0","type":"rich","title":"DC Crime Stack Chart","description":"This interactive stacked bar chart visualizes 2017 crime counts by offense type across Washington, D.C. police service areas (PSAs). Built with D3.js (v3), the visualization uses a stacked layout to aggregate five offense categories—such as burglary and motor vehicle theft—along a horizontal axis, with PSA segments stacked vertically. Users can hover over bars to see tooltips with exact counts via d3-tip, or hover over the color legend to highlight specific crime types while dimming others. The chart also includes a dropdown to switch between yearly datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/71efb8b1deb74b03be50b7434448161b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
