This 3D bar chart visualizes the total number of speakers for seven languages across six Indian regions, with each series representing a region. The chart uses the Highcharts library with the highcharts-3d module to render vertical, stacked columns in a three-dimensional space, configured with alpha, beta, and depth options. Data is hardcoded as arrays of coordinate-value pairs, with categories on the x-axis, totals on the y-axis, and a z-axis labeled "Various languages." The visualization employs grouped, padded columns to distinguish regional datasets.
