{"version":"1.0","type":"rich","title":"Crossfilter","description":"This visualization uses the Crossfilter library with D3.js v4 to explore a dataset of over 3 million flights through four linked bar charts showing time of day, arrival delay, distance, and date. Users can brush any chart to filter the flight list below, which updates all other charts and the selection count via crossfilter’s dimensions and groups. The charts use `d3.scaleLinear` and `d3.scaleTime`, with bar charts rendered as SVG and brushed ranges applying crossfilter filters. Data is loaded as CSV from a GitHub Pages-hosted JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-ebe599703421757852d36bcf71174dfc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
