This visualization shows a line chart of calorie counts for campus snack items, with each point labeled by snack name and a hover tooltip displaying the exact calorie value. The chart uses D3 v7 with SVG rendering, employing `d3.csv` to load data, `d3.scalePoint` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to generate the orange line connecting red data points. Grid lines and a rotated x-axis label enhance readability, while mouseover events trigger the tooltip transitions.
