Interactive pie and bar
This interactive dashboard links a bar chart and a pie chart to explore export data by state and sector. Hovering over a bar filters the pie chart and legend to show the sector breakdown for that state, while hovering over a pie segment updates the bars to display the selected sector’s values. The visualization uses D3 v3 with SVG and animated transitions, rendering a histogram by ordinal and linear scales, and a pie chart with a legend that updates frequencies and percentages.
