FAQ
- How is it different from a line chart?
- Area charts add a translucent fill under the line, stressing the “amount”.
- Can I adjust the fill opacity?
- This version uses a semi-transparent preset palette and doesn’t support custom opacity yet; adjust the exported PNG with an image tool if needed.
- Will my data be uploaded?
- No. Parsing and rendering happen locally in your browser; your data never leaves your device.
