The ICE 7 Line Chart visualizes the number of accidents in Texas over time as an orange line on an SVG canvas. It uses D3 v5 (imported via `d3` object) to load a CSV dataset from a GitHub gist, parse years with `d3.timeParse`, and render axes with `axisBottom` and `axisLeft` functions. The chart displays a time-scaled x-axis and a linear y-axis with gridlines, and the line is drawn using the `line()` generator with `scaleTime` and `scaleLinear` for coordinate mapping.
