  3. 3 Download the rendered chart as PNG, ready for slides or docs.

Why use this tool

  • Powered by Chart.js, loaded lazily — page stays light until you scroll the preview.
  • RFC 4180 CSV parsing — quoted commas and embedded newlines handled correctly.
  • No upload — your data never leaves the browser.
  • Multiple series per chart — every numeric column becomes a separate line.

Frequently asked questions

Where can I get more chart types?

See the <a class="underline" href="/bar-chart-maker">Bar Chart Maker</a>, <a class="underline" href="/pie-chart-maker">Pie</a>, <a class="underline" href="/doughnut-chart-maker">Doughnut</a> and <a class="underline" href="/scatter-plot-maker">Scatter</a> tools — they all share the same CSV input shape.

What if my data is in JSON?

Convert it first with the <a class="underline" href="/csv-to-json">CSV ↔ JSON</a> converter, then paste the CSV here.

Why are some cells ignored?

Non-numeric cells in data columns become null. The first column is treated as a label string, all other columns must parse as numbers to plot.

What is Line Chart Maker?

A Line Chart Maker is a tool that turns pasted CSV data into a line chart directly in the browser. It plots one or more data series as connected points along an axis, offers a slider to smooth the curve between points, and exports the rendered result as a PNG image, with all processing happening client-side and nothing uploaded to a server.
