A scatter plot displays the number of reviews per day across a year, with each circle representing a single day and its review count. The visualization uses D3 v5 with an SVG rendering approach, employing `scaleLinear` for both axes and `axisBottom`/`axisLeft` for tick marks. Data is loaded from a CSV file via `csv`, and the plot includes axis labels and a title. Circles are styled with semi-transparent steelblue fill to show density variations.
