This line chart displays the count of restaurants per year, using a smooth curved line to emphasize trends over time. The visualization is built with D3 v5, employing `scaleLinear`, `scaleTime`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to generate an SVG path. Data is loaded from a CSV file via `d3.csv` and rendered with a green, thick stroke. The chart includes labeled axes and a title, with gridlines and margins styled for clarity.
