A scatterplot visualizes fixation coordinates from a data.csv file, plotting x and y positions as steelblue circles that animate into place sequentially. A green path connects the points in data order, repeatedly drawing itself via a stroke-dasharray attrTween. The chart uses d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.line, with hover interactions that enlarge and recolor circles. SVG rendering includes labeled axes and a title.
