The visualization displays a grid of generalized histograms for eight weather metrics, including windSpeed, humidity, and temperatureMax, sourced from a JSON dataset. Each chart renders bars using SVG rectangles, with a dashed line and label marking the mean. Built with React and D3 v5, the code employs `d3.json`, `d3.histogram`, and `d3.scaleLinear` to compute bins and scales, while `d3.axisBottom` handles the x-axis labels.
