Visual representation simplifies large datasets
-
Highlights trends, patterns, and outliers
-
Supports data-driven decision making
-
Enhances presentation quality for reports or dashboards

|---|---|
| Combo Chart | Combine two chart types (e.g., column + line) for dual analysis |
| Waterfall Chart | Show cumulative effect of sequential data (profit/loss analysis) |
| Funnel Chart | Visualize stages in a process (sales funnel) |
| Radar / Spider Chart | Compare multiple variables across categories |
| Histogram | Show frequency distribution of numeric data |
| Box & Whisker | Display data distribution, median, quartiles, and outliers |
| Surface Chart | Visualize data trends across 3D space (advanced 3D data) |
| Treemap & Sunburst | Display hierarchical data in nested rectangles or circular format |
