{"version":"1.0","type":"rich","title":"d3Edge_V5-dataLoading","description":"This example demonstrates a modular data-loading pattern for D3.js v5, showing how to decouple CSV and GeoJSON fetching from chart rendering. It defines a `dataManager` module that uses `d3.csv` with async/await and `d3.json` to load external files, applying custom cleaning functions to the CSV data. The module dispatches custom events (`dataLoading`, `dataReady`) via `d3.dispatch`, and uses a custom replacement for the removed `d3.rebind` to expose event handling. The page displays a loading message until data arrives, then instructs users to inspect the cleaned data via `getCleanedData()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0eda23a6f93c42aa85155456ce7fc563?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
