This area chart displays the number of Hulu subscribers over time, with the title “subscribers incresing frequency” and axes labeled “Years” and “number_of_subscribers.” It uses D3 v5 APIs such as `d3.area`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render an SVG path with an orange fill, based on CSV data loaded via `d3.csv`. The chart applies `d3.curveBasis` for smoothing and includes custom tick formatting with `d3.format`.
