Understanding Heat Maps
What is a Heat Map?
A heat map is a two-dimensional visualization where values are represented by colors. The intensity or hue of the color indicates the magnitude of the value, making it easy to spot patterns and trends in large datasets.
When to Use Heat Maps
- Visualizing matrices of numerical data
- Identifying patterns and correlations
- Comparing categories across multiple variables
- Analyzing temporal or spatial distributions
- Exploring clustering in data
Best Practices
- Choose appropriate color scales for your data
- Consider standardizing values for better comparison
- Use clustering to reveal patterns
- Include clear labels and legends
- Consider the number of categories for readability
