## About

## What it does
Bar Chart Generator creates a bar chart image from your data and returns it as either a pre-signed image URL or a binary download, depending on the endpoint you use.

Send a `title` and a `data` array of bar objects. Each bar can include a `label`, `value`, and optional `color` as a 6-character hex value without `#`. You can also set `theme` to `light` or `dark`, and fine-tune the chart with `options` such as `width`, `height`, axis font sizes and colors, spacing, bar width, background padding and color, title styling, and canvas color.

Use it when you need charts for dashboards, reports, email exports, admin panels, or generated documents. The same input structure works whether you want a shareable chart link from `/link` or a direct image file from `/download`.

Bar Chart Generator is a fit for applications that need consistent, programmatic chart rendering without building chart logic in the client.
