A line graph, also known as a line chart or line plot, is a type of chart used to visualize data points connected by straight line segments. It is a fundamental tool in data analysis and visualization, particularly effective for showing trends over time or across a continuous variable. The horizontal axis, or x-axis, typically represents the independent variable, such as time, quantity, or temperature, while the vertical axis, or y-axis, represents the dependent variable, which is being measured or observed.

Line graphs are created by plotting individual data points on a two-dimensional plane and then connecting these points sequentially with straight lines. This visual connection helps to illustrate the rate of change between consecutive data points, making it easy to identify patterns, fluctuations, and overall trends in the data. Multiple data sets can be displayed on the same line graph by using different colored or styled lines, allowing for direct comparison of their respective trends.

The primary advantage of a line graph is its clarity in depicting trends and changes over a continuous range. It is commonly used in fields such as economics, finance, science, and statistics to present information such as stock prices, temperature variations, population growth, or experimental results. The simplicity and effectiveness of line graphs make them an indispensable tool for understanding and communicating data-driven insights.
