This line chart displays weekly temperature variations over time, with points connected by a smooth curve and circular markers showing individual readings. Temperature values appear on the y-axis and time along the x-axis, formatted by day of the week. Built with React and D3 v6, it uses `scaleTime`, `scaleLinear`, `line`, and `curveNatural` to generate the SVG visualization, pulling data from a CSV file containing San Francisco week temperatures.
