This dashboard example shows how linked views can be used for interactive data exploration. A bar chart of state frequencies and a pie chart with a legend are initially displayed together, and hovering over a bar in the histogram updates the pie chart and legend to show that state's breakdown by low, mid, and high segments. Conversely, hovering over a pie slice triggers a transition that updates the histogram to reflect the frequencies of that segment across the states. The code uses D3 v3 with an SVG rendering approach, relying on d3.scale.ordinal, d3.scale.linear, and transition methods to animate the changes.
