[scatter-color-mapped] Color-Mapped Scatter Plot

[MarkusNeusinger]

Plot Request

Scatter plot with a third variable encoded as color using a colormap. Includes colorbar for reference.

Use Cases

• Visualizing 3 variables simultaneously
• Showing intensity or magnitude on scatter
• Geographic or temperature data

Expected Features

• Continuous colormap (e.g., viridis)
• Colorbar with proper labels
• Clear axis labels

✅ Spec ID: scatter-color-mapped

Rationale: This spec extends the basic scatter plot by encoding a third continuous variable as color with a colorbar, which is a distinct visualization pattern commonly used for geographic, temperature, and intensity data.

Add label approved to begin generation.

scatter-color-mapped: Color-Mapped Scatter Plot

Description

A scatter plot that encodes a third continuous variable using a colormap, allowing visualization of three dimensions on a 2D plane. This visualization is essential for exploring multivariate relationships where the third variable represents intensity, magnitude, or any continuous measurement. A colorbar provides a reference scale for interpreting the color values.

Applications

• Visualizing temperature distribution across geographic coordinates
• Showing intensity or magnitude patterns in scientific measurements
• Displaying correlation strength or significance levels across data points

Data

• x (numeric) - First variable plotted on the horizontal axis
• y (numeric) - Second variable plotted on the vertical axis
• color (numeric) - Third variable encoded as color intensity
• Size: 50-500 points recommended for clear visualization
• Example: Random data with a third variable representing intensity or magnitude

Notes

• Use a perceptually uniform colormap (e.g., viridis) for accurate value interpretation
• Colorbar should have clear labels indicating the mapped variable and its units
• Points should have moderate size to ensure color visibility
• Consider transparency if points overlap significantly
