### 8. **Scatter Plots**
– **Focus:** Revealing correlations between two variables.
– **Use Case:** Useful for spotting trends, anomalies, or clusters in large datasets, such as scientific research findings or economic data analysis.
### 9. **Histograms**
– **Focus:** Illustrating the distribution of numerical data through frequency intervals.
– **Use Case:** Great for understanding the spread and concentration of data points, particularly useful in statistical data analysis.
### 10. **Box Plots**
– **Focus:** Summarizing data using quartiles.
– **Use Case:** Perfect for comparing distributions of data samples and understanding their spread and central tendency.
### 11. **Tree Maps**
– **Focus:** Displaying hierarchical data by size.
