Data Visualization is the process of turning raw data into visual formats like charts, graphs, or maps to make it easier to understand and analyse. It helps people spot patterns, trends, and insights quickly.
Examples:
- Bar charts: Showing sales comparisons across different months.
- Heatmaps: Highlighting areas with the highest activity, like website clicks.
- Scatter plots: Revealing relationships between variables, such as income and spending habits.
In AI, data visualization is often used to explore datasets, communicate findings, or evaluate model performance.
