Showing gzip sizes in the bundle analyzer

I've kinda replaced bundlephobia with esbuild's bundle analyzer personally, but one thing I miss from bundlephobia is seeing the min+gzip size, which doesn't seem available in esbuild's bundle analyzer.

I'm thinking the gzip size for each file can be listed fairly naturally in the modal that is opened on click.

For the entire bundle it seems trickier UI-wise, maybe there could be a button that toggles between min and min+gzip sizes, both in the header, in tooltips, and in the size used to render the chart itself.

Start at esbuild's bundle analyzer and trace how the clicked-file modal, bundle header, tooltips, and chart size are produced. The work is done when min+gzip sizes are available for individual files and the entire bundle, with the proposed display or toggle behavior covered consistently.
