This example shows a data-visualization of hiking trail data from the HikingProject API, mapping trail names, lengths, and summaries into a custom layout. The code defines a `HikingProject::Trail` class that parses trail attributes and stores them in a class-level array, enabling aggregation of multiple trail records. It demonstrates a programmatic approach to structuring dataset properties for later rendering, though it does not include explicit drawing code. The visualization likely relies on a JavaScript library such as D3.js for scaling or positioning, but the provided snippet focuses solely on Ruby object initialization and data collection, leaving the visual output implicit.
