This animated scatterplot visualizes a time series of 50 data points, connecting them in chronological order with a smooth line. Each dot represents a moment in time, with its vertical position encoding the "rate" value while the x-axis maps temporal progression. The visualization uses D3 v4's SVG rendering to draw a continuously-updating path that links each point to the next, creating the sense of drawing a connected line through the data. As time advances, the line extends to incorporate new points while earlier segments remain visible, producing a dynamic "connect-the-dots" effect. The animation highlights the temporal flow and changing values across the dataset, with the line's movement revealing patterns in the rate changes over time. The visualization uses a minimal, uncluttered aesthetic that focuses attention on the trajectory of the data points.
