This is a map of Chromium binary, showing how many bytes do our various bits of code contribute to the final executable. It's built using webtreemap and bloat.
It's 100MB of json file, be patient-- a static preview image (in grayscale) is being shown while it's loaded. Once the entire map is loaded, click on a box to zoom in, click on the outermost box to zoom out.

It looks the Chromium binary size is now about 3 times larger than it was 5 years ago.
