This example displays temperature readings (T and Tw) across dates and times as a bar chart. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis temperature range and `scaleBand` for the categorical y-axis combining date and time values. The chart includes `axisLeft` and `axisBottom` to display the scales, while bars are drawn as SVG rectangles colored steelblue. Data is loaded from a local CSV file and processed by converting temperature values to numbers before binding to the visualization.
