Final answer:
Line graphs and pie charts both can be shared publicly, pull data from multiple sources, and be customized, but only line graphs are designed to display information over a period of time, whereas pie charts are not.
Step-by-step explanation:
When comparing the features of line graphs and pie charts, we can ascertain a few critical similarities. Firstly, A. Both can be shared publicly. This is a common feature as most chart types can be disseminated through various media for public consumption. Secondly, B. Both can pull data from multiple sources. The data fed into these charts can come from various databases or datasets. Lastly, D. Both can be customized. Both line graphs and pie charts offer various customization options, from color schemes to data markers, allowing the presenter to tailor the charts to their specific communication needs.
It's important to note that C. Both are designed to display information over a period of time is not accurate for both. While line graphs are particularly adept at showing trends and changes over time, pie charts are best suited for displaying a snapshot of how a whole is divided into parts at a given point in time, not over a series of time intervals. Hence, the features A, B, and D are accurate for both line graphs and pie charts, while feature C is not.
