Chart Maker
Paste a table from your spreadsheet, pick the column of labels and the series, and choose bars, a line or a pie. The page reads every number exactly, asks when a number could mean two things, and shows blank cells as gaps instead of zeros.

A pie shows the parts of one whole, from one series. For change over time or a comparison, use bars or a line.

Data in the chart
Put the charts and their source behind one link
Publishing results or a campaign report? The organizer can gather the charts and the public source of the numbers in a VISU Link, so everyone opens the same current page.
How to use it
- Copy the cells from Excel, Google Sheets or Numbers, first row with the column names, and paste them in the table box.
- Check the table as read below the box: numbers show how they were read, and anything that could not be read is marked.
- Pick the column of labels, tick the series to draw and choose bars, line or pie.
- Add a title and an axis label, choose whether the values are numbers, money in any currency or percentages.
- Download the chart as SVG for a document or a slide, or as PNG for a message or a post.
Examples
Monthly report
Six months of website visits and newsletter sign-ups as grouped bars, with the April gap shown as a gap because the value was not recorded.
Budget split
One column of costs by department as a pie, with each part as a percentage and the amount in the legend.
Survey trend
A line for each answer across four survey rounds, with the value printed on every point.
Questions
How do I make a bar graph from a table?
Paste the table with the labels in one column and the numbers in the next ones. Bars is the default type: every ticked column becomes one colour, and the chart updates as you edit the table.
What if my numbers use a comma for decimals?
Both 1,234.56 and 1.234,56 are read. When one cell proves the style, for example 2.500,75, the whole table is read that way and the page says so. When a number such as 1.234 could mean two things and nothing in the table decides it, the chart waits until you choose the decimal separator.
When should I use a pie chart?
Only when the values are parts of one whole, such as a budget split or the share of answers. The page warns you when the labels look like months or years, or when percentages do not add up to 100, and it refuses negative values.
Are empty cells treated as zero?
No. A blank cell is a gap in a line and a missing bar, and it shows as no value in the data table. Type 0 where the value really is zero.
Is the chart accessible?
The SVG has a title and a description that name the series and the highest and lowest values, and the page shows the same numbers as a data table under the chart.
Is my data uploaded?
No. The table is read and drawn in your browser and nothing you paste or open is sent to VISU. Close the page and it is gone, so keep the SVG or PNG.
