Key Concepts

Data Visualization

Data visualization is the practice of converting raw data into graphical representations such as charts, graphs, and maps. This technique helps in identifying patterns, trends, and outliers, and makes complex data more accessible and understandable.

Line Graph

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is especially useful for showing trends over time or continuous data, making it ideal for visualizing how a particular variable changes.

Time Series Data

Time series data refers to data points collected or recorded at successive, evenly-spaced points in time. This type of data is common in many fields and is essential for analyzing trends and patterns over a period, which can be effectively represented using line graphs.

Interpreting Data Tables

Interpreting data tables involves extracting, organizing, and understanding numerical information presented in rows and columns. Being able to accurately read and analyze tables is crucial for translating the data into other forms of representation like graphs, aiding in overall data analysis.
