Fork of 3D chart
This example displays multi-series bar charts in an interactive 3D scene, with each bar representing a person’s age and height. The visualization uses the d3-x3d library, which bridges D3’s data joins with X3DOM’s WebGL rendering, while relying on d3.csv to load data from a remote GitHub gist. After fetching the CSV, the code parses rows into key-value pairs and calls the barChartMultiSeries component, which draws the 3D bars and updates the scene. The chart is attached to a div via `datum()` and invoked with a standard D3 selection call.
