📘 What is a Line Graph?
A line graph (or line chart) is a type of chart used to display information as a series of data points connected by straight line segments. Line graphs are particularly useful for visualizing trends over time and comparing multiple data series.
Line graphs plot each data point at the intersection of an x and y value and then connect these points with lines, making it easy to see patterns, trends, and relationships in the data.
