This interactive scatterplot compares Star Wars starships by cost, length, and crew, using the SWAPI dataset. Users can dynamically select which numeric attribute maps to the x-axis, y-axis, and circle size, with axes and legend labels updating accordingly. A checkbox filters out expensive capital ships, and a smooth D3 transition animates the repositioning of circles when a new column is selected. The visualization is built with D3 v5 and rendered as an SVG, featuring a size legend for the third variable.
