Visualization
The process of representing data or information graphically to make it easier to understand, analyze, and interpret
- It transforms raw data into visual formats such as charts, graphs, maps, and diagrams.
- This allows users to identify patterns, trends, and insights that might be difficult to discern from text-based data alone.
A line graph showing the trend of sales over time is a simple visualization that helps businesses track performance and make informed decisions.
Two-Dimensional Visualization
Two-Dimensional Visualisation
The representation of data or information in a flat (two-dimensional) space, such as a graph, chart, or image.
Two-dimensional visualization is a powerful tool for communicating complex data in a simple, visually appealing format.
Examples of 2D-Visualization
Scatter Plots
- Scatter plots are used to visualize the relationship between two variables.
- Each point on the plot represents a pair of values, with the x-axis representing one variable and the y-axis representing the other.
A scatter plot showing the relationship between hours studied and test scores for a group of students.
