What is the difference between a chart and a graph?

Figure out what data you need to achieve your goal. Different types of charts and graphs use different kinds of data. Graphs usually represent numerical data, while charts are a visual representation of data that may or may not use numbers. So, while all graphs are a type of chart, not all charts are graphs.

What are the different types of graphs?

Popular graph types include line graphs, bar graphs, pie charts, scatter plots and histograms. Graphs are a great way to visualize data and display statistics. For example, a bar graph or chart is used to display numerical data that is independent of one another.

What is a directed graph?

Later, we'll see directed graphs, in which relationships between vertices don't necessarily go both ways. In an undirected graph, an edge between two vertices, such as the edge between Audrey and Gayle, is incident on the two vertices, and we say that the vertices connected by an edge are adjacent or neighbors.

What is a graph used for?

Graphs are used to express relationships between objects. The objects are nodes, and the edges are the relationships. The edges can be given weight to express something about the relationship. I'll only mention two major applications that are seen in computer science, but there are many more.
