This interactive parallel coordinates chart visualizes a dataset of cars and their specifications, such as fuel economy, horsepower, and weight. Each car is represented by a line connecting its attribute values across multiple vertical axes. Users can drag axes to reorder them and use brush controls on each axis to filter which vehicles remain highlighted, with the background context paths hidden while dragging. The visualization is built with D3.js v3, using SVG for rendering, `d3.svg.axis` for axes, and `d3.behavior.drag` and `d3.svg.brush` for interaction.
