Data representation is all about showing information in a clear and visual way so it’s easier to understand and analyze. Instead of reading long tables of numbers, we use charts, graphs, and diagrams to quickly spot patterns, trends, and insights.
Different types of data call for different types of visual representation. Choosing the right one can make your data more meaningful and impactful.

📊 Common Types of Data Representation:
1. Bar Charts
Bar charts show comparisons between categories using rectangular bars.
Use it when you want to compare values across different groups (e.g., sales by product).
2. Pie Charts
Pie charts show how a whole is divided into parts.
Each slice represents a percentage of the total.
Best for showing proportions or percentages (e.g., market share).
3. Line Graphs
Line graphs show trends over time using connected data points.
Ideal for tracking changes over days, months, or years (e.g., monthly revenue growth).
4. Histograms
Histograms look like bar charts but are used to show the distribution of continuous data.
Great for understanding how data is spread out (e.g., exam scores, age ranges).
5. Scatter Plots
Scatter plots show relationships between two variables using dots.
Useful for spotting correlations or trends (e.g., hours studied vs. test score).
6. Tables
Tables display exact numbers in rows and columns.
Helpful when details matter and you need to show raw values.
7. Box Plots (Box-and-Whisker)
Box plots show the spread and skewness of data, highlighting medians and outliers.
Useful for comparing distributions across groups.
8. Heat Maps
Heat maps use color to show values within a matrix or grid.
Often used in website analytics, performance tracking, or survey responses.
9. Infographics
Infographics combine visuals, icons, and brief text to explain complex data in a simple and engaging way.
Perfect for reports, presentations, or sharing insights with a general audience.
