2. Line Charts

Line charts are ideal for displaying data trends over time. They connect individual data points with lines, making it easy to see changes at a glance.

Advantages	Disadvantages
Great for showing trends	Can become cluttered with too many lines
Good for continuous data	Less effective for categorical data

3. Pie Charts

Pie charts display data as slices of a whole, making it easy to see proportions. They are best used when you want to show relative sizes of parts to a whole.

Advantages	Disadvantages
Visually appealing	Hard to interpret with many categories
Good for showing percentages	Not effective for precise comparisons

4. Scatter Plots

Scatter plots are used to show relationships between two numerical variables. They can reveal correlations, trends, and outliers.

Advantages	Disadvantages
Excellent for identifying correlations	Can be difficult to interpret with large datasets
Displays distribution of data	Requires careful scaling of axes

5. Heat Maps

Heat maps use color to represent data values in a matrix format. They are effective for showing the intensity of data at different intersections.
