This visualization compares three climate variables—temperature, humidity, and wind speed—across 150 days of recorded data. Temperature and humidity appear as red and blue line series, while wind speed is shown as green bars, creating a combined chart. The visualization uses D3 v7 (d3.csv, d3.line, d3.scaleLinear) to load the climate_data.csv file and render the SVG elements, including axes, gridlines, and a legend. The approach overlays multiple mark types to highlight relationships between the three measurements over time.
