On the left, this visualization displays the raw, unformatted text of a personal workout log, detailing exercises, repetitions, and poundage. The right side shows the output of a custom `parse` function, which converts that text into a JSON array of objects, each with `exercise`, `reps`, `poundage`, and optional `notes` fields. The code uses D3's `text` method to load `data.txt` and `select` to populate the two panels.
