Chart Maker

Chart Maker turns a small table of numbers into a clean, readable chart in seconds. Type into the spreadsheet-style grid, or copy a block of cells from Excel, Google Sheets or Numbers and paste it into any cell. The chart redraws as you type, so you can try a bar chart, a line, a doughnut, a radar or a funnel and keep whichever tells the story best.

It is made for the everyday jobs: a sales chart for a monthly report, survey results for a school project, a pie of where the budget goes, a radar comparing two products, a sign-up funnel, or a scatter plot with a trend line. You control the title, axis titles, legend position, number format (plain, short like 1.2K, currency or percent), decimal places and data labels.

What makes it different: the default colours are the Okabe–Ito set, chosen so people with common colour blindness can still tell the series apart. Every chart comes with a plain-English description you can copy as alt text, and a table view of the numbers for screen-reader users. Charts are drawn by our own code, saved as vector SVG, sharp PNG or a print-ready PDF, and your data never leaves your device.

1. Type your data into the grid: series names along the first row, labels down the first column. Or choose an example from "Examples…" to start from.
2. To bring in a spreadsheet, copy the cells and paste into the top-left cell (paste into another cell to fill from there), or press "Import CSV".
3. Pick a chart type: Bar, Line, Area, Pie, Doughnut, Radar, Funnel or Scatter, then choose options such as Horizontal, Stacked or Smooth curves.
4. Under "Labels and style", add a title and axis titles, move the legend, change the colours and set the number format.
5. Press "PNG (2× sharp)" for slides, "SVG" for design apps, "PDF" for print, or "Copy image" to paste it into a message.

• Eight chart types: bar (vertical or horizontal, side by side or stacked), line, area, pie, doughnut, radar, funnel and scatter
• Radar charts with one filled shape per series, and funnels that show each stage’s share of the first and the step-by-step conversion
• Spreadsheet-like grid: Enter and arrow keys move between cells, add or remove rows and columns, swap rows and columns
• Paste from Excel, Google Sheets, Numbers or CSV; reads "$1,250", "12.5%", "(200)" and European "1.234,5" correctly
• Eight colour sets, including two colour-blind-safe ones and a greyscale set for black-and-white printing, plus your own colour for each series
• Number formats: plain, short (1.2K, 3.4M), any currency, or percent, with a choice of decimal places
• Data labels, smooth curves that never overshoot your data, a least-squares trend line with R² for scatter plots
• White, dark or transparent background, and four sizes from square to a wide banner
• Save as PNG at 1× or 2×, SVG, or a one-page PDF with a 300 DPI image; copy the image or the SVG code
• Accessible: a written summary of the chart (copyable as alt text) and a data table view

• Pie, doughnut and funnel charts show one column at a time; use "Column to show" to switch. A funnel keeps your rows in the order you typed them.
• For a scatter chart, put numbers in the first column: they become the X values, and each other column is a set of Y values.
• Use the greyscale palette, or turn on data labels, if the chart will be printed in black and white or photocopied.
• Paste the description from "Copy as alt text" into the alt text box when you add the image to a web page, email or document.
