Venn, funnel, waterfall and Pareto, next to the everyday ones. Exports real SVG.
Most free chart tools give you a bar, a line, a pie, and a PNG. This one adds the shapes people actually search for and hands back vector SVG you can scale or edit, using a palette that has been machine-checked for colourblind readability rather than picked by eye.

SVG stays crisp at any size and can be edited in Illustrator, Figma or Inkscape. PNG is a flat image.
Search for a pie chart maker and you get Canva, Adobe Express, and a dozen others. Search for a waterfall chart maker, or a Pareto, or a funnel, and the field thins out immediately. That is odd, because those are the shapes that answer the questions people actually bring to a chart.
| Type | The question it answers | When to reach for it |
|---|---|---|
| Waterfall | How did we get from this number to that number? | Revenue bridges, budget variance, anything where the story is the steps between two totals rather than the totals themselves. |
| Funnel | Where are people dropping out? | Signup flows, checkout, hiring pipelines. The drop between stages is the finding, so the shape should make it unmissable. |
| Pareto | Which few causes account for most of the problem? | Support tickets, defect types, complaint categories. Bars sorted descending plus a cumulative line shows the 80/20 point directly. |
| Venn | What do these groups share? | Overlapping audiences, skill sets, feature comparisons. Usually qualitative, which is why this one takes text per region rather than numbers. |
| Bar / Column | Which is bigger? | The honest default. If you are unsure which chart to use, it is almost always this one. |
| Line / Area | What changed over time? | Only for time or another continuous sequence. Categories on a line chart imply a progression that is not there. |
| Pie / Donut | What share of a whole? | Only when parts sum to a meaningful 100%, and only with a handful of slices. Past five or six, a bar chart reads faster. |
Roughly one man in twelve has some form of colour vision deficiency. A chart whose series are distinguished by red and green alone is unreadable to a chunk of any audience, and that is a design failure rather than an accessibility footnote.
The palette here was run through a validator, not chosen by eye. Every adjacent pair is checked for perceptual separation under normal vision and under simulated protanopia, deuteranopia and tritanopia, plus a lightness band, a chroma floor, and contrast against the chart background. Both the light and dark versions pass. There is also a texture option, which adds a directional hatch to each series so the chart survives being printed in black and white or read by someone who sees no colour difference at all.
Values are labelled directly on the marks by default for the same reason: identity should never depend on colour alone. A legend plus direct labels plus an optional data table means the chart is readable three different ways.
Most free chart tools export PNG. A PNG is a grid of pixels at one fixed size, so putting it in a slide deck and projecting it, or printing it, produces soft edges and fuzzy text.
SVG is the drawing instructions, not a picture of the result. It stays razor sharp at any size, the text stays real text that can be searched and selected, and it opens in Illustrator, Figma, Inkscape or a code editor where every element can still be moved and restyled. If you need a flat image afterwards the PNG button is right there, but exporting the vector first means never having to remake the chart because you need it bigger.
Keep going without re-uploading — your image carries over to the next tool automatically.
