This stylized line chart visualizes San Francisco temperature readings over a week, with a smooth curve connecting data points and circular markers for each observation. Time is plotted on the x-axis using a d3.scaleTime with weekday tick labels, while temperature appears on the y-axis via d3.scaleLinear. The React components (AxisBottom, AxisLeft, Marks) use SVG rendering with d3.line and curveNatural to generate the path, and circles include native title tooltips. Styling comes from Poppins font, custom tick colors, and a teal stroke on the marks.
