This example visualizes the structure of Anson’s BASH profile, a dotfile configuration, as a static code map. It shows the file’s organization, including alias definitions, prompt-color settings, and Git helper functions, along with their corresponding shell commands. The visualization is rendered by parsing the raw gist text and using a custom layout algorithm that groups related lines and highlights syntax elements. It relies on the `d3.hierarchy` and `d3.treemap` APIs to position nodes, with `d3.select` and `d3.attr` for styling. The source data is the plain-text `.bash_profile` file from the gist, and the rendering approach is a tree map where each leaf represents a command or setting.
