This scatter plot shows the relationship between packet length and anomaly scores in network traffic data. The visualization maps packet length on the x-axis and anomaly scores on the y-axis, with each circle representing a data point. The code uses d3.csv to load data from a GitHub gist, d3.scaleLinear for both axes, and d3.axisLeft and d3.axisBottom to render the scale ticks. Circles are appended to an SVG container using data joins, with blue fill and 50% opacity to show overlapping points.
