This interactive dashboard visualizes the budgets and worldwide grosses of Marvel Cinematic Universe movies as a pie chart and histogram. The pie chart breaks down each movie’s total into three categories—Budget, Domestic Gross, and Worldwide Gross—with hover interactions on either chart updating the complementary visualization. Built with D3 v3 inside a React framework, it uses `d3.scale.ordinal`, `d3.scale.linear`, and SVG transitions to animate changes, while a legend with frequency and percentage totals provides additional context. Data is embedded directly in the script.
