NY Motorcycle Crashes Loading Data
This example demonstrates loading and displaying a subset of NYC motorcycle crash data. The visualization shows the raw dataset as a JSON-formatted list of objects, with each row containing attributes like vehicle make, model, driver sex, and contributing factors.

Once loaded, the code converts the `UNIQUE_ID` field to numeric values and re-renders the data via `d3.select` and `join` operations.
