Q: Can I edit the chart after exporting? Image exports (PNG) are final. To make changes, modify the chart in Kontext and export again. Data exports (CSV, JSON) can be edited in other tools.
Q: Where do exported files go? Exports download to your browser’s default download location with names like “chart-name.png” or “chart-data.csv”.
