This interactive visualization displays a live-updating line chart where each click of the “Next Point” button appends a new random temperature value to the series. Built with React and D3 v5, the SVG chart uses `d3.scaleLinear` for both axes and a D3 line generator with `curveNatural` to render the smooth path. The code defines reusable axis components and dynamically adjusts the data array via React state, with axes and labels styled using Poppins typography.
