Question

1. why do we have different types of graphs?

Explanation:

Different graph types exist because each is optimized to present specific kinds of data and highlight distinct patterns, relationships, or trends. For example, bar graphs compare discrete categories, line graphs track changes over time, pie graphs show proportions of a whole, and scatter plots reveal correlations between variables. Using the right graph makes data easier to interpret and communicate effectively.

Answer:

We have different types of graphs because each type is designed to best display specific categories of data, emphasize unique trends, relationships, or comparisons, and make information easier to interpret and communicate clearly for different analytical or explanatory goals.
