This interactive dashboard links a bar chart of 2019 export totals per state with a pie chart and legend that break down each state’s exports by agricultural, industrial, and livestock categories. Hovering over a bar updates the pie chart and legend to reflect that state’s sector frequencies, while hovering over a rectangle highlights it in blue. Built with React and D3 v3, the visualization uses ordinal and linear scales, SVG transitions, and mouseover/mouseout handlers to coordinate the views.
