This interactive 3D bar chart visualizes accident distribution by day of the week and month, loading user-supplied CSV data via a file input. The chart is rendered with the Highcharts library, specifically its `highcharts-3d.js` module, which applies 3D rotation (alpha and beta angles) and depth. PapaParse parses the CSV, then jQuery selects the container and builds the chart with `chart.type: 'column'`. Twelve monthly series are stacked and grouped across seven weekday categories, with each bar’s height reflecting the count of records per `acci_time` date.
