This scatterplot displays temporal progression of fixation coordinates from a CSV file. Each circle represents a data point, while a line path connects them in sequence, with an animated stroke-dashoffset effect revealing the trajectory over time. Using D3 v5, the code leverages `scaleLinear`, `axisLeft`, `axisBottom`, `extent`, and `line` to construct the chart. The SVG rendering includes circular points, labeled axes, and a title, with smooth transitions applied via D3’s `.transition()` method for both point placement and path drawing.
