This example presents a bar chart visualization using D3 v5, loading automotive data from a CSV file hosted on VizHub. The SVG-based chart defines margins and computes inner dimensions, then sets up a linear scale for horsepower values with a domain derived from the dataset. The code uses d3.csv to fetch the data and d3.scaleLinear for the x-axis scale, though the rendering logic remains incomplete at the time of this snapshot.
