Understanding Treemaps

A treemap is a data visualization technique used to display the hierarchical structure of information and the proportions of values in a dataset. The unique feature of treemaps is that they utilize space efficiently by representing data using nested rectangles.

Analysis of Options

1. As numerical values: This option suggests that treemaps represent data using numbers, but that's not how they visualize data.

2. As data points on a line: This option describes linear representation, which is contrary to the treemap's spatial depiction.

3. As columns: This could refer to bar charts or similar, which does not apply to treemaps.

4. As rectangular shapes: This option correctly identifies that treemaps visualize data using rectangles whose size is proportional to the value they represent.

Conclusion

In summary, treemaps display the proportion of data using rectangular shapes that vary in size based on the underlying data values. Therefore, the correct answer is:

Final Answer

As rectangular shapes.
