{"version":"1.0","type":"rich","title":"d3Edge_V5-dataLoading-v0.4","description":"This example demonstrates a modular data-loading system for D3.js v5, built around a custom dispatch event manager. It loads a CSV file of Zurich transit delay data and a separate TopoJSON geographic file, applying a cleaning function to parse timestamps and coordinates. The code uses asynchronous `d3.csv` and `d3.json` loading with custom `dataLoading`, `dataReady`, and `geoReady` events, and exposes methods like `getCleanedData()` for console inspection. The visualization itself remains a placeholder, showing a loading message and instructions while the data pipeline runs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e79209c96e5499fbb3a4f7a7055817b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
