This interactive visualization displays San Francisco weather data, letting users explore relationships between date, temperature, and other climate variables. The chart allows switching between line and area chart types, with dropdown menus for selecting x and y attributes. Built with React and D3 v5, it renders SVG paths using d3.line and d3.area, with smooth transitions via .attrTween and d3.interpolateArray. A tooltip appears on mouseover, showing precise inverted coordinate values via d3.mouse and scale.invert.
