What kind of data visualization would be most suitable for high-dimensional datasets?
- Bar chart
- Parallel coordinates or a scatter plot matrix
- Pie chart
- Scatter plot
Visualizing high-dimensional datasets (those with many variables) can be challenging. However, techniques like parallel coordinates or a scatter plot matrix can help. Parallel coordinates plot each variable on a separate column, and lines connecting the columns represent individual data points. A scatter plot matrix shows all pairwise scatter plots of the variables.
