This example displays a time-series line chart of review counts from 1976 to 2025. The visualization uses D3 v5 with an SVG rendering approach, employing `d3.csv` to load data and `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` to construct the plot. The chart features labeled axes, a title, and gridlines, with the review count plotted against the year.
