Line graphs are essential tools for comparing quantitative data across one or more categories over a specified time frame. They effectively illustrate trends by plotting data points on a Cartesian plane, where the x-axis represents time, and the y-axis reflects the quantitative values. This visual representation allows for clear insights into changes and patterns over time, making it easier to analyze data and make informed decisions.
