Chart (Dataset, Axis) Example
Demonstrates Cartesian plotting with interactive styling and configuration.
Trends and patterns are invisible in raw logs. Charts visualize X/Y datasets to reveal the story behind the data.
Features Demonstrated
-
Dataset Types: Line charts and Scatter plots.
-
Markers: Braille patterns, dots, blocks, and bars.
-
Axis Configuration: Controlling labels, bounds, and alignment (Left/Center/Right).
-
Legend: Positioning the legend in any of the four corners or hiding it based on constraints.
