This example presents three interactive charts for multidimensional data exploration: a bubble chart, a line chart, and a scatterplot matrix. The bubble chart visualizes earthquake data with tooltips on hover and supports filtering by region via a color legend built with d3-legend. The line chart displays three series with hover tooltips on individual points. The scatterplot matrix uses d3 to show pairwise relationships across multiple dimensions. All visualizations leverage React and D3 for rendering and interactivity.
