When comparing line graphs and pie charts, which statement is true for both?

When considering the capability of line graphs and pie charts, the statement that both can be shared publicly highlights a significant aspect of data visualization. Line graphs and pie charts, often created using various software tools or platforms, can be generated and distributed in formats that allow for public access. This feature is particularly useful in educational settings, where teachers might want to share data visualizations with students or the broader community.

Line graphs effectively depict trends over time or continuous data, while pie charts break down a single data set into its categorical parts. They both serve different purposes in data representation but share the ability to be published and shared widely, enhancing their accessibility and potential impact for informative or educational purposes.

The ability to display data in 3D may not necessarily apply to all instances of line graphs or pie charts as it depends on the specific tools used. User authentication is not a requirement for either type of visualization in most cases, particularly when dealing with basic graphics or public sharing. Additionally, both line graphs and pie charts can represent multiple datasets, albeit in different ways, and are not limited to just one. Thus, the shared public accessibility of both formats stands out as the only universally true statement among the options presented.
