Which two visualizations could be used to simplify a pie chart displaying customer types?

Using a bar chart and a treemap are effective alternatives to simplify a pie chart displaying customer types.

The bar chart effectively represents categorical data, making it easy to compare the size of different customer segments side by side. This direct comparison is often clearer than the segmented view of a pie chart, where the distinction between slices can sometimes be misleading, particularly when segments are of similar size.

On the other hand, a treemap provides a visually appealing alternative by using nested rectangles to represent hierarchical data. Each rectangle's size indicates the relative proportion of each customer type, which allows for quick visual analysis of the distribution of customers without the potential confusion of pie slices, especially when there are many categories.

In contrast, line charts and histograms focus on trends over time or distributions, which may not be appropriate for categorical comparisons like customer types. Similarly, area charts and scatter plots are used for different types of data visualization, such as trends and relationships, rather than for simple categorical comparisons. Finally, while pareto charts can show the most impactful categories and bullet charts provide performance against a goal, neither is primarily aimed at simplifying the direct visual representation of categories like the bar chart and treemap do.
