Scatter Demo
Source: scatter_demo.f90
Demonstrates enhanced scatter plotting with color mapping, variable marker sizes, and bubble charts.
- Basic scatter plots: Simple point visualization
- Bubble charts: Variable marker sizes based on data values
- Color mapping: Colors based on data values with colorbar
- Multiple marker shapes: Different point styles
- Scientific data visualization: Proper scaling and presentation
The demo generates scatter plots showing different visualization techniques for multi-dimensional data presentation.
