How it works
- Enter item names and values in "label,value" format, one item per line, and each item's share of the whole is calculated automatically and drawn as a pie chart.
- Each share is computed using the sum of all values as the denominator, so the slices are proportioned to add up to 100%.
- Negative values are treated as 0, and the chart is shown when the total of the values is greater than 0. It works well for visualizing budget breakdowns, survey tallies, sales mix, and similar data.
- Slices are sorted from largest to smallest value and color-coded; items with a very small share have their in-chart percentage label omitted, but every item still appears in the table and legend.
- You can rewrite the input as many times as you like, and adding or removing items updates the pie chart and the share table instantly.
