○ data about data
○ linked lists
○ bar charts

Explanation:

• For the first question: A line graph is specifically designed to show trends over time or a continuous variable. A bar chart is better for comparing discrete categories. A pie chart is for showing proportions of a whole. While "it depends on the data" is a valid general statement, in the context of showing trends, the most specific and commonly - accepted answer is the line graph.
• For the second question: Metadata is defined as "data about data". It provides information that describes other data, such as its origin, format, and meaning. Linked lists are a data structure in computer science. Bar charts are a data visualization tool. Survey answers are the results of a survey.

Answer:

• First question: Line graph
• Second question: Data about data
