What are the differences between various data visualization techniques?

There are several data visualization techniques, each suited for different types of data and insights. For example, bar charts are great for comparing quantities, while line graphs are ideal for showing trends over time.

Can you explain when to use a pie chart versus a bar chart?

Certainly! Use a pie chart when you want to show parts of a whole, especially when there are few categories. Bar charts are better for comparing multiple categories or showing changes over time.

What about scatter plots? When should I use them?

Scatter plots are useful for showing the relationship between two continuous variables. They can help identify correlations or trends in the data.

Are there any visualization techniques that are considered outdated?

Yes, some techniques like 3D pie charts and excessive use of 3D effects can be considered outdated as they often confuse rather than clarify data.
