This D3.js (v7) visualization shows the relationship between movie runtime, rating, and votes, with genre as a categorical color channel. It presents a scatterplot of movie data loaded from a GitHub-hosted CSV file, with axes for runtime and rating. The code uses D3 APIs including `d3.csv`, `d3.extent`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.select` to build the SVG chart. It also computes summary statistics like mean and median rating using `d3.mean` and `d3.median`. The page includes a summary box with data dimensions and field ranges.
