Generate Chart from Table Data

This automation transforms spreadsheet-like input into a visual chart. It starts with raw data, uses ChatGPT to extract labels and values into structured JSON, then creates an HTML-based Chart.js line chart. This chart is rendered in a headless browser, and the canvas is captured as a base64-encoded PNG image. Finally, the base64 buffer is converted into a clean image. Ideal for anyone looking to turn raw or tabular data into visual reports quickly and automatically.
