# Chart

Charts are built with `Vtiful\Kernel\Chart`, fed series via `series()` / `categories()`, then inserted into a worksheet.

> Build the `Chart` instance into a variable first, then call `output()` on the workbook. Chaining `(new Chart())->series()->toResource()` inline triggers a double-insert warning.
