{"version":"1.0","type":"rich","title":"NY Car Crashes Loading Data","description":"This example demonstrates asynchronous data loading in D3 v7. It fetches a CSV file containing 500 records from NYC OpenData’s Motor Vehicle Collisions – Vehicles dataset, filtered to sedans. The visualization initially shows a loading state, then parses the CSV with `d3.csvParse` and converts the UNIQUE_ID field to numeric values using a `for` loop. The processed data is stored in a state object and displayed as a JSON-formatted text preview inside a `<pre>` element via `d3.select` and `.text()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1069c161cb0e42508973a45e23531a0a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
