{"version":"1.0","type":"rich","title":"CrashData","description":"This interactive map visualizes the distribution of motor-vehicle collisions across New York City, with each crash represented as a point on a geographic grid. The code uses D3.js's `d3.geoPath` to render city boundaries and `d3.select` with a custom color scale to encode crash density by neighborhood. Data is loaded from a local CSV via `d3.csv`, and the rendering relies on the Canvas API for efficient point plotting. A brush interaction, implemented through `d3.brush`, allows users to filter collisions by time of day or day of week, dynamically updating the displayed points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27d0e6c45f1f4fc1b6528275dbfd2c6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
