Show how shares change over time

The example shows the world’s electricity generation by source from 2000 to 2025 (data: Ember, Energy Institute). Watch solar and wind slowly take their slice — a change that is much easier to feel in motion than in a table. Works for vertical social videos and widescreen slides alike.

Features

Enter raw numbers — the percentages and the animation are done for you.

How to make a pie chart race

Just three steps.

1

Prepare your data

Put item names in column A, an optional image URL in column B, and one column of values per year (or month) after that. No need to calculate percentages.

2

Upload or paste it

Load a CSV or Excel file, or type and paste your data into the table in the tool.

3

Style it and export

Pick pie or donut, adjust colors and labels, preview the animation, then press “Save video” to export an MP4 or WebM file.

FAQ

Do I have to calculate the percentages myself?
No. Enter raw values such as sales or generation, and the tool calculates each item’s share of the period total. Data that is already in percent works too. Labels can show the percentage, the value, or both.
Won’t it get cluttered with many items?
Set the number of slices to show and the smaller items are grouped into “Other”, with a name and color you can change. Labels can also be placed outside the slices with leader lines.
Do I need an account? Can I use the videos commercially?
No account is needed, and you can use your videos commercially on YouTube, social media, in presentations and in class. Please credit GraphRace Studio in the video or its description.
Can I export it as a video?
Yes. Press “Save video” to export an MP4 or WebM file. MP4 plays on iPhone and Android.
Is my data uploaded anywhere?
No. Everything runs in your browser and nothing is sent to a server.
