Correct answers: A, B, D
Explanation
For visualizing sentiment distribution and trends over time, bar charts, line graphs, and pie charts are the most appropriate choices. Bar charts and pie charts provide a clear representation of sentiment distribution across categories, while line graphs excel at showing changes and trends over time. Scatter plots and heatmaps, while useful in other contexts, do not directly address the core need of conveying sentiment distribution or time-based trends.
- A. Correct.
A bar chart is effective for displaying the count of positive, neutral, and negative sentiments, making it easy to compare sentiment categories at a glance.
- B. Correct.
A line graph is an excellent choice for showing trends, such as how the average sentiment score changes over time.
- C. Incorrect.
While a scatter plot is useful for exploring relationships between variables, it is not the most intuitive way to convey sentiment distribution or trends over time.
- D. Correct.
A pie chart is a good way to illustrate the proportional distribution of sentiment categories, providing a clear visual of how the sentiments are divided.
- E. Incorrect.
A heatmap of sentiment across geographic regions might be useful in some contexts, but it is not directly relevant to understanding sentiment distribution or trends over time.
