The diagrams showing just how much faster Git performs than Subversion were originally created using the Google Charts API, in b6d341c (first graphs and new services, 2012-04-30). In the meantime, the Google Charts API joined so many other things in the Google Graveyard (see https://killedbygoogle.com/ for more details). This means that the diagrams 404ed, and users were left wondering what should have been demonstrated on this page. But when a door closes, another door opens, and there are wonderful contenders in this time and age, and we do not even have to display static images, we can switch to proper, Javascript-backed charts where you can even hover over the chart and see the exact number! So let's do that. Based on https://www.chartjs.org/, reimplement those charts. That also offers a wildly improved readability of the entire thing, compared to the somewhat cryptic Google Chart URLs. This fixes git#1862. Signed-off-by: Johannes Schindelin <[email protected]>

I don't really like to bring in a client side library to render some bar charts we can render statically instead. Currently I'm experimenting with another idea. I'll let you know if it works out. |

When the Google Charts API entered the Google Graveyard, the diagrams on the "About - Small and Fast" page got broken.
This fixes #1862.
As a bonus, this allows readers to see the actual numbers when hovering over the bars:
