This example visualizes Munich transit delays per line, with each circle representing a trip. The x-axis encodes timestamp, the y-axis encodes line, and circle size encodes delay value, revealing temporal patterns in service reliability. It is built with the Vega-Lite API, which generates charts from JavaScript objects, and uses D3’s `csv` loader to fetch data from a GitHub-hosted CSV file. The visualization is rendered as an interactive SVG with tooltips, styled via a custom configuration.
