This interactive scatterplot visualizes the relationship between temperature (°C) and humidity (%) from a CSS color dataset, styling each data point as a circular mark. Built with React and D3 v7, the code uses `scaleLinear`, `extent`, and `format` to map the values, while `csv` loads the data from a remote URL. The SVG rendering includes custom axis components and hover tooltips that display temperature values. The visualization uses a Poppins font and muted teal marks on a clean background, with labels for both axes.
