This basic line plot displays the number of online orders received over time, with dates on the x-axis and order values on the y-axis. The visualization uses D3.js v4 to load CSV data from a GitHub repository, parse dates with `d3.timeParse`, and render the chart as an SVG. Axes are created with `d3.axisBottom` and `d3.axisLeft`, while the line itself is drawn using `d3.line` with a red stroke. The chart is sized with explicit margins and scales using `d3.scaleTime` and `d3.scaleLinear`.
