CSV to Line Chart — Free Online Tool
Line charts are ideal for showing how a value changes over an ordered dimension — time series data, version numbers, experiment iterations. Upload your CSV and pick the column that represents the X axis (e.g., date, month, version) and the Y axis (e.g., revenue, latency, count).
The chart renders with markers at each data point and connecting lines. Hover over any point to see the exact value. Export as PNG for reports or SVG for further customization.
Frequently asked questions
Can I plot multiple lines from one CSV?
Multi-series line charts are on the roadmap. Currently a single Y column is plotted per chart.
Does it support date/time on the X axis?
Yes. Plotly automatically detects ISO date strings and renders a proper time axis with smart tick labels.
Next step
Charting a CSV export means the data already went stale.
Every refresh is another export, another upload, another chart. Connect the source itself to your AI agent with Sequel and ask for the chart against live data.
