A multi-line chart displays the frequency of three named Atlantic storms from 1995 to 2016, with each storm represented by a colored line over a time-based X axis and a frequency Y axis. The visualization loads CSV data from a GitHub gist, groups and parses it with `d3.group` and `d3.timeParse`, and renders SVG paths using `d3.line` and `d3.scaleTime`. A legend and axis labels clarify the series, while a categorical color scale assigns each storm a distinct color.
