A line chart tracks monthly order counts across twelve months, from January’s 120 to December’s 480, with each data point marked by a blue dot and an orange line. The chart uses D3 v7’s `d3.csv` to load the data, `d3.scalePoint` and `d3.scaleLinear` for axes, and `d3.line` for the path. Tooltips via SVG `<title>` elements show exact values on hover. The SVG rendering includes rotated month labels and styled axes.
