Area Chart Maker FAQ

What CSV structure should I use?
Use one category column (such as month or quarter) and one or more numeric columns — each numeric column becomes a series.
When should I use stacked area?
Use stacked when you care about composition — how channels or segments add up to a total. Use overlapped when you want to compare absolute values.
Why use smooth curves?
Smooth curves reduce visual noise and make trends easier to read. Turn it off when you need exact category-to-category transitions.
Is my data private?
Yes. CSV parsing and rendering all happen in your browser — nothing is uploaded.
Which formats can I export?
PNG and SVG download, plus copy-to-clipboard for direct paste into slides and docs.
