In the debate, the most preferred graphics for showing the data are not mentioned. There are many graphics that can be used to evaluate the performance of the food products in comparison to each other, given current data. It is easier to spot patterns in a data set when you have a visual graph. A higher number of sales may not necessarily indicate an error. A visual graph is necessary to make it easier to comment on the trend of a data set. The creation of a visual chart to help with the discussion about the sale figures for this restaurant is essential.

A line chart is a great way to show the evolution of a data set over time. The line chart can be used by an analyst to determine how the restaurant performed in different months. This presentation shows the sales figures for various foods in a month using a line chart. The selected visuals may help to clarify the data. It is because patterns are easily visible and can be compared. It’s easy to identify which type of meal was most popular over the four-month period. A donut chart was chosen to represent the available data. It is easy to identify which item contributed most to the total sales for the past four months. The chart cannot compare the monthly sales performance of each item. The chart may not be useful in such situations, as it might make comparisons difficult.
