3. Data Analysis: Applying analytical techniques to identify patterns, trends, and correlations within the data.

5. Data Visualization: Utilizing charts, graphs, and other visual elements to convey insights effectively.

6. Interactive Features: Adding interactivity to reports, allowing users to explore data, drill down into details, and ask ad-hoc questions.
