CSV to Area Chart — Free Online Tool
Area charts are like line charts with the area below the line filled in. They emphasize volume and cumulative magnitude rather than just the trend direction — useful for showing total traffic, cumulative revenue, or running totals over time.
Upload a CSV, choose an ordered X column and a numeric Y column, and the filled area chart is rendered. The fill color uses the primary palette color at 20% opacity to keep the chart readable.
Frequently asked questions
When should I use an area chart vs a line chart?
Use an area chart when the filled volume is meaningful (e.g., cumulative sales). Use a line chart when only the trend direction matters and the area would be misleading.
