This stylized line chart visualizes temperature readings over a week, sourced from San Francisco weather data, with the x-axis showing time in days and the y-axis showing temperature. The chart uses a natural cubic spline curve via d3.line’s curveNatural to create a smooth line, with circular data points that display tooltips on hover. The visualization is built with React, renders as SVG, and employs d3.scaleTime for the time axis and d3.scaleLinear for the temperature scale, styled with a Poppins font and custom color scheme.
