This example animates the drawing of a line chart, transitioning each data point from the bottom of the plot to its correct position over time using a staggered delay. The visualization uses Apple’s stock closing price data, rendered with a custom easing function and a line path. Built with React, the code leverages Observable’s `d3.select`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, `d3.line`, and a timer to orchestrate the animation, with axes and a styled steelblue stroke.
