This example demonstrates how to integrate D3’s data-joining and animation capabilities with React’s component lifecycle to render dynamic bar charts. Using SVG for scalable, resolution-independent graphics, the visualization shows bars that animate in height while displaying numeric labels. The chart leverages D3 v6 scales and axes to map data to positions, with smooth transitions triggered by state changes in React. Marks such as rectangles and text are bound to data via keys, while channels like position, length, and color encode the dataset. The animation uses D3 transitions inside React’s render cycle, highlighting how the two libraries can work together for interactive, web-based visualizations.
