This example displays raw workout log text on the left and its parsed JSON structure on the right. The D3.js code uses `d3.text` to load `data.txt`, then a custom `parse` function splits each line by `@` and `x` to extract exercise name, reps, poundage, and notes into an array of objects. The left panel shows the original input, while the right panel uses `select` and `.text` to display the parsed output.
