{"version":"1.0","type":"rich","title":"Combining data from multiple fetches d3","description":"This example demonstrates how to coordinate multiple asynchronous data fetches in D3.js by combining parking facility data from two separate RDW API endpoints. It uses the `d3.json` method with a CORS proxy URL to retrieve both datasets, then employs `Promise.all` to wait for both fetches to complete before processing the combined results. The code logs the overview of parking locations, selects the first ten facilities, and matches them with their corresponding data sources. The visualization itself is minimal, displaying only console output rather than rendered graphics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/998f8f50a1484e36a934815ab532e193?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
