What is Graph and its types?

In discrete mathematics, a graph is a collection of points, called vertices, and lines between those points, called edges. There are many different types of graphs, such as connected and disconnected graphs, bipartite graphs, weighted graphs, directed and undirected graphs, and simple graphs.

What are the different types of chart?

Four of the most common charts are:
  • Histogram.
  • Bar chart.
  • Pie chart.
  • Line chart.

Which graph is best?

Line graphs can also be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.
