About the Chart Maker
Paste or type your data, choose a chart type and get a clean picture you can save straight away. Bar charts and line charts take a label and one to six number columns, so you can compare several series with a legend. Pie charts show the share of each row, with an optional hole for a donut. Scatter plots take x and y pairs, tidy their axes and can draw a straight trend line through them. You can add a title and axis names, pick a colour set and choose wide, square or banner size. The finished chart downloads as a sharp PNG at double size or as SVG you can edit in a vector program. Limits: up to 60 rows and six number columns for bar, line and pie, and 500 points for scatter. Charts have a white background and there is no dark theme or animation.

- 2Type or paste your data, one row per line: a label then numbers, or x then y for a scatter plot. A first row of names becomes the legend.
- 3Add a title and, for bar, line and scatter charts, names for the axes.
- 4Pick a colour set and size, and switch values, grid lines, donut or trend line on or off.
- 5Press Download PNG or Download SVG, or copy the SVG code.
Choosing the right chart
A bar chart compares amounts between separate groups, such as sales by month or votes by party. A line chart suits values that follow one another in order, most often over time, where the slope tells the story. A pie chart shows how a whole splits into parts, and works best with up to six or seven slices that add up to something meaningful. A scatter plot shows how two measured values relate, such as hours studied and exam score.
If you are unsure, start with a bar chart. It is the easiest to read, and readers compare bar lengths more accurately than slice angles.
Entering your data
The data box reads plain text, so you can type it or paste it from a spreadsheet.
- Bar, line and pie: a label, then one or more numbers on each line
- First line of names (optional): Month, Sales, Costs puts Sales and Costs in the legend
- Scatter: x, y on each line, with an optional first line such as Hours, Score
- Decimals use a dot, such as 2.5. Do not put commas inside numbers
- Negative values are fine for bar, line and scatter charts, but not for pie
Saving and using the picture
The preview is exactly what you download. PNG works in Word, PowerPoint, email and social media. SVG stays crisp at any size and can be opened in design programs to change fonts or colours. On a computer, hover over a bar, point or slice to see its exact value.
To work out the numbers that feed a chart, use the Average Calculator or the Standard Deviation Calculator, and for percentages of a whole, the Percentage Calculator. To tidy a spreadsheet export before charting, see the CSV Tools.

Frequently asked questions
How do I make a bar graph from my data?
Choose Bar and type one row per bar, with a label then a number, like Jan, 120. Add more number columns to draw side-by-side bars, and a first row of names to get a legend. The chart updates as you type, and you can save it as PNG or SVG.
Can I paste data from Excel or Google Sheets?
Yes. Copy the cells and paste them into the data box. Tabs between columns are read as they are, and commas and semicolons work too. Write thousands without commas, like 1000, because a comma separates columns.
What data does a pie chart need?
One label and one positive number per row. Each slice is its share of the total and is labelled with its percentage. Negative values cannot be drawn in a pie, and if you give several number columns only the first is used.
How do I make a scatter plot with a trend line?
Choose Scatter, enter one x, y pair per row and tick Show straight trend line. The dashed line is the ordinary least-squares line through all points. It describes a straight-line fit only, so a curved pattern will not be captured.
Should I download PNG or SVG?
Use PNG for documents, slides and social posts. It is saved at twice the chosen size, so it stays sharp when shown large. Use SVG when you want to edit colours or text in a vector program, or need the chart to scale to any size.
Is my data uploaded anywhere?
No. The chart is drawn by your browser from the text in the box, and the PNG is made on your device. Nothing is sent to a server, and nothing is saved when you close the page.
Why does the tool show an error for my data?
It tells you which row is wrong, for example a cell that is not a number or a row with extra columns. Fix that row and the chart returns. Empty cells are not skipped, so type 0 where a value is zero.
