My first Line Chart temperature
This line chart displays temperature variations over time for multiple cities, using color-coded lines to distinguish each city. The visualization includes a smoothed curve fitting via the `curveBasis` function and a color legend for city identification. Built with D3 v5, the chart uses SVG rendering and reads data from a CSV file, with animated transitions in the legend. The time and temperature axes are labeled, and the data is nested by city using the `nest()` function before being plotted.
