This example presents a 3D scatter plot of car specifications, visualizing horsepower, mileage, and price for different brands. Each car is represented as a colored marker, with color encoding brand identity: Honda appears cyan, Mercedez green, and Ferrari red. The visualization is built with Plotly.js, specifically using the `Plotly.newPlot` API to render a `scatter3d` trace. Data is loaded via D3.js (`d3.csv`) from a cars dataset, with marker colors assigned by iterating through the brand column and pushing corresponding color values into an array.
