This example demonstrates animated bar charts comparing monthly revenue and profit data from a JSON file. The visualization toggles between the two metrics every two seconds, with bars smoothly transitioning their heights and colors using D3 transitions. It implements interactive tooltips using d3-tip, triggered by mouseover and mouseout events. The SVG is rendered using D3 v5 within a React framework, featuring axes, labels, and a legend that updates dynamically based on the displayed metric.
