{"version":"1.0","type":"rich","title":"Tester","description":"This visualization compares the number of traffic accidents that occurred in darkness versus daylight conditions using a simple bar chart. It filters a CSV file of Chicago traffic crash records into two categories based on lighting conditions, then renders the counts as animated steelblue bars. The chart is built with D3 v7, using `d3.scaleBand` and `d3.scaleLinear` for axes, and includes interactive tooltips on hover. The SVG rendering and bar transitions are handled entirely through D3’s standard data-join and selection methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a992548664764bd38a114c58e7e0d964?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
