This scatter plot visualizes the relationship between the number of food items in a restaurant and the total food price increase percentage, with each circle representing a data point. The visualization uses D3 v7 and the `select`, `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and `scaleOrdinal` APIs to render. The chart includes labeled x and y axes and shows a color legend, though all marks are filled blue and the legend appears unused in the main plot. Data is loaded from a CSV file hosted on GitHub.
