Frequently Asked Questions

Is my data sent to your servers?

No, all data processing and chart generation happens entirely within your browser using JavaScript. Your data is never uploaded or stored on our servers, ensuring complete privacy.

Can I download the chart as an image?

Yes, once the chart is generated, you can click the "Download PNG" button in the toolbar to save the chart as a transparent, high-quality image file.

What library is used to render the charts?

We use Chart.js, a powerful, open-source HTML5 charting library, to render responsive and interactive charts directly on the HTML canvas.

How many data points can I visualize?

While there is no strict limit enforced by the tool, rendering performance and visual clarity may degrade if you attempt to plot thousands of data points on a single chart. For best results, summarize or aggregate large datasets before plotting.
