A scatterplot displays fixation coordinates from a CSV file, with x and y axes labeled and points rendered as steelblue circles. Each point enters sequentially through a 1-second transition with a 100-millisecond delay. A green line connects the points in data order, using a monotone curve and animating its stroke-dasharray via `transition.attrTween` to create a continuous drawing effect. The visualization uses d3.scaleLinear for axes, d3.axisBottom and d3.axisLeft with gridlines, and d3.line for the path, all rendered in SVG.
