This visualization displays the temperature in Brussels over a seven-day period, with each hour represented as a point on a scatter plot. The data, sourced from Meteo Blue, is loaded from a CSV file and rendered as red circles using the D3.js v6 library. The code uses D3's `scaleLinear` for scaling, and `axisLeft` and `axisBottom` functions to create the axes. While the code contains references to displacement and horsepower, the actual plot correctly maps timestamps and temperature values.
