Coordinates Scatterplot
This example visualizes fixation coordinates from a CSV file as a scatterplot, with each point representing an eye-tracking sample. The animation sequentially reveals points over one second, followed by a connecting line that traces the path between fixations in data order. The visualization is built with D3 v5, using SVG elements, scaleLinear axes, and the transition API for the animated appearance. Axis labels, tick marks, and a title are also rendered, with styling applied via CSS.
