ECharts Polar Bar Chart
A bar chart drawn on a polar coordinate system rather than a Cartesian grid — bars sweep outward from the centre, with category around the angular axis and value along the radial axis. ECharts treats `polar` as a first-class coordinate system so all the standard axis features (la

When to use this template
This visualization excels at revealing patterns, peaks, and troughs in quantitative data that naturally cycles or has a directional component. It allows for quick comparison of independent values around a conceptual circle, making the adjacency of the axis's start and end points visually intuitive. Analysts use it to identify cyclical trends or directional biases where a linear axis might obscure the continuity.
- Data with a clear cyclic or directional categorical dimension.
- Quantitative values associated with each category.
- Independent values, not components of a total sum.
- When angular axis ends are conceptually adjacent.
- Moderate number of categories (e.g., 12-365) for readability.
- When comparing magnitudes across categories is the primary goal.
