I often use treemaps for quick datavis on hierarchical data, like this (ancient) analysis of Chrome binary size: https://neugierig.org/software/chromium/bloat/ https://neugierig.org/software/chromium/bloat/. As part of that made a little web-based treemap widget called "webtreemap" and published a version that I use in unix pipelines. It accepts data on stdin and dumps self-contained HTML on stdout. # install program: $ npm install --global webtreemap # pipe any utility that outputs size+hierarchy data into it: $ du | webtreemap > demo.html # interact in browser: $ open demo.html
