This animated pie chart visualizes the price distribution of gadgets from a CSV file, with each segment labeled and a corresponding color-coded legend. The visualization uses D3 v7's `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` APIs, rendering SVG paths and text elements. Interactive tooltips appear on mouseover, displaying the gadget name and price. The chart is generated within an 800×500 SVG canvas, with the legend positioned separately and arcs animated from the center.
