Difference between "chart" and "graph"

The word "chart" is usually used as a catchall term for the graphical representation of data. "Graph" refers to a chart that specifically plots data along two dimensions.

All graphs are a type of chart, but not all charts are graphs.

What is Graph?
Graphs mainly focus on raw data and depict the trend overtime-related to such data. A two-dimensional graph shows the relationship between the data through a line, curve, etc., using the horizontal line along the bottom (called X-axis) and vertical line up the side (called Y-axis). As per the Advanced English Dictionary, “A Graph is a mathematical diagram that shows the relationship between two or more sets of numbers or measurements.” A graph allows the user to easily represent the values in the data through a visual representation.




What is Chart?
A chart is a type of representation of large sets of data, which makes the user understand the same better. Using the same helps predict existing data and forecast future data based on the present data pattern. A chart can take the form of a diagram, a picture, or a graph. We can transform datasets into a meaningful display of information using charts.
