A 3D Bar Chart is a three-dimensional data visualization that can display data distribution in 3D space. It is ideal for displaying 2D data matrices (e.g., time period x category, region x product), where bar height represents value magnitude. This tool is built on ECharts GL and supports interactive mouse drag rotation and zoom. Supports both manual data point entry and bulk CSV import, with customizable colors, shadows, grids, and other styles. Use cases include: sales data analysis, multi-dimensional data comparison, scientific experiment data visualization, etc.
