Which feature is true for both line graphs and pie charts?

Both line graphs and pie charts have the capability to pull data from multiple sources, making them versatile tools for visualizing information. This feature allows users to aggregate and represent varied data in a single chart, facilitating comparison and analysis across different datasets. For instance, you might create a line graph to show trends over time using data from distinct spreadsheets or databases, or you could combine data sets for a pie chart to represent the parts of a whole derived from different sources.

The other options do not accurately apply to both types of charts. Line graphs are particularly suited for illustrating trends and changes over time with detailed numeric data, while pie charts are often more effective for showing proportions within a single dataset. Additionally, while charts can be generated easily in various applications including Google Docs, this feature is not unique to both line graphs and pie charts, as the generation process can differ in complexity depending on the data involved. Lastly, creating these visualizations does not typically require complex coding; they can be produced through user-friendly interfaces in software tools.
