📊 Chart & Graph Maker

A chart you can actually put in a document

Most free chart sites hand you a screenshot sized web image with their logo in the corner. This one exports a PNG up to 3600 pixels wide, a genuine vector SVG and a one page PDF, all drawn from the same shape data, so what you see in the preview is exactly what lands in the file. Nothing is watermarked and nothing is uploaded. The whole page runs in your browser, so a client's revenue figures stay on your machine.

Bar and column chart maker

Columns for comparing a handful of things, horizontal bars when the labels are long names rather than short months. Add a second or third series and they sit side by side automatically. Switch to stacked when the parts add up to a meaningful whole, such as revenue split by product line, and to 100% stacked when the mix matters more than the total, which is the right chart for showing that mobile traffic went from a third of the total to over half.

Pie and donut chart generator

Pie and donut both read the first series only, because a pie can only show one set of numbers split into parts. Each row becomes a slice and the labels come from the first column. Turn value labels on and every slice big enough to hold a label is marked with its share as a percentage, while very thin slices are left unlabelled so the text does not collide. A donut is the same chart with the middle cut out, which is the shape most brand decks and dashboards use now because the labels sit better against it.

Line, smooth line and area graphs

Line charts for anything measured over time, smooth line when the trend matters more than each individual reading, area when you want the volume under the line to feel substantial. Stacked area is the time series version of a stacked bar: use it when several streams add up to one total you also care about, like traffic by channel across twelve months.

Radar and scatter

A radar chart, sometimes called a spider chart, compares several things across the same set of scored dimensions, which is why it turns up in skills assessments, competitor comparisons and product scorecards. Scatter plots take the first column as the horizontal value, so give it numbers rather than month names, and each remaining column becomes a separate cloud of points.

Getting your numbers in

Select a block in Excel, Numbers or Google Sheets, copy it, click any cell in the grid and paste. The block lands in place and the grid grows to fit it, up to 200 rows and 12 series, and the page tells you if anything past those limits was left out. A dropped or opened CSV works the same way, and commas, semicolons, tabs and pipes are all detected automatically. Currency symbols, thousands separators and percent signs in your figures are read and ignored, so pasting 1,240 or $8,600 or 42% all works.

PNG, SVG or PDF

The PNG is rendered at up to three times the chart size, which is enough to print or to drop into a slide without it going soft. The SVG is real vector output, so it stays sharp at any size and every element can still be edited in Illustrator, Figma or Inkscape. The PDF is a single A4 page with the chart fitted and centred, for a report appendix or something you intend to print. Text in the SVG uses whatever font is installed on the machine viewing it, so a very unusual font on your computer may be substituted on someone else's. The PNG and the PDF bake the text into the image as it looks here, so those two are identical everywhere.
