This line chart visualizes one week of one-way network delay data (in milliseconds) from San Francisco, sourced from Data Canvas - Sense Your City. It plots delay values over time using a smooth curve (d3.curveBasis) on an SVG. The code builds scales with d3.scaleTime and d3.scaleLinear, renders axes with d3.axisBottom and d3.axisLeft, and generates the line with d3.line. Data is loaded via d3.csv and parsed into dates and numbers before rendering.
