Chart Builder — turn any CSV into a chart

Upload a CSV file (or paste data), pick a chart type, choose the columns you want to plot, and download the result as a PNG or SVG image. Everything happens in your browser — your data never leaves your device.

Supported chart types

  • Line — trends over an ordered axis (time, categories). Optionally smooth the line into a spline.
  • Bar — compare values across categories. Plot several series side by side (grouped) or stack them.
  • Scatter — show the relationship between two numeric variables as a cloud of points.
  • Area — like a line chart but filled to the baseline, good for emphasizing magnitude.
  • Pie — show how a single numeric column breaks down across the categories in your X column.
  • Histogram — show the distribution of one or more numeric columns by binning their values.
  • Box plot — summarize a distribution with median, quartiles and outliers; great for comparing groups.

How to use it

  1. Upload your data. Drag and drop a CSV file, click Choose file, or paste comma/semicolon/tab-separated data into the textarea. The delimiter and header row are detected automatically, and both US (1,234.56) and EU (1.234,56) number formats are handled.
  2. Pick a chart type. Switch types at any time — the chart re-renders instantly.
  3. Choose columns. Select an X column for the categories or horizontal axis, then click one or more numeric columns to plot as Y series. For pie charts, the X column supplies the slice labels and a single numeric column supplies the values.
  4. Customize. Give the chart a title, stack bars, or smooth lines.
  5. Download. Use the PNG image or SVG vector buttons to save the chart. PNG is exported at 2× resolution for crisp screenshots; SVG stays sharp at any size and is ideal for print or further editing in design tools.

Privacy

This tool is fully client-side. The CSV you upload is parsed and rendered with JavaScript in your own browser using Plotly.js. Nothing is transmitted to any server, so it is safe to use with private or confidential datasets.

Tips

  • Numeric columns are detected automatically (a column counts as numeric when at least 80% of its non-empty cells parse as numbers). Only numeric columns can be used as Y series.
  • To compare several metrics, select multiple Y columns — each becomes its own series with a distinct color and a legend entry.
  • Histograms and box plots ignore the X column; they work directly on the distribution of the selected numeric columns.
