Final answer:
An XY (scatter) chart is best suited for analyzing the relationship between sales performance and population density across different sales regions.
Step-by-step explanation:
Dominique is aiming to analyze sales performance across different regions in relation to population density. The best type of chart to represent this data and conduct this type of analysis would be an XY (scatter) chart. This is because scatter charts are excellent for showing the relationship between two variables, in this case, sales performance and population density. Each point on the scatter plot represents a region with its respective sales figure and population density value.
Comparatively, line charts are better for showing trends over time, while pie charts are suited for displaying how a whole is divided into parts - which would not efficiently represent the relationship between sales and population density. The column chart could show data for individual regions, but doesn't convey correlations as effectively as a scatter chart. Therefore, the XY (scatter) chart is the most appropriate choice for Dominique's analysis.
Using a scatter plot will help Dominique visualize the data and identify any trends or patterns. It will show the distribution of sales performance across different population densities and allow her to assess which sales regions perform best in comparison to population density.
