This example displays an interactive 3D bar chart built with D3.js v2 and jQuery. It renders an SVG-based visualization where bars are grouped by categorical x-axis values, with drop shadows applied via SVG filters to create a 3D effect. The chart uses ordinal and linear scales to map data, and includes custom axis tick formatting for captions. The code initializes on document ready, transforming input data and building the chart within a scrollable container.
