Your sensitive financial or user data is never uploaded to any server. The chart engine processes your files entirely locally in your web browser.

Frequently Asked Questions (FAQ)

How should I format my JSON data?

Your JSON should be an array of objects. The first key-value pair in each object is treated as the label (X-axis), and the remaining numerical values are treated as the datasets (Y-axis).

How should I format my CSV data?

The first line must contain your headers. The first column represents your labels (e.g., Jan, Feb, Mar), and subsequent columns are your data points separated by commas.

Can I upload files directly?

Yes! Use the "Upload File" button to load local .csv, .json, or .txt files directly into the editor. The tool will parse the contents instantly.

Which chart type should I use?

Use Bar charts for comparing quantities across categories, Line graphs for showing trends over time, and Pie/Doughnut charts for illustrating proportions of a whole.

Is there a limit to how much data I can chart?

While there is no hard limit because processing is done locally, charting hundreds of data points on a single pie or bar graph can make it unreadable. For best visual results, aggregate your data into 5-15 categories.
