  • Identify trends and patterns
  • Communicate findings effectively
  • Facilitate data-driven decision-making

Common Visualization Techniques

There are several widely used visualization techniques in business analytics. Each technique serves different purposes and is suited for various types of data.

1. Bar Charts

Bar charts are used to compare different categories of data. They display rectangular bars with lengths proportional to the values they represent.

Advantages Disadvantages
Easy to understand Not suitable for large data sets
Good for categorical data Can become cluttered with too many categories

2. Line Charts

Line charts are ideal for showing trends over time. They connect individual data points with lines, making it easy to observe changes.

Advantages Disadvantages
Effective for time series data Can be misleading if data points are too few
Shows overall trends clearly Not suitable for categorical comparisons

3. Pie Charts

Pie charts represent data as slices of a circle, illustrating the proportion of each category relative to the whole.

Advantages Disadvantages
Visually appealing Hard to interpret with many categories
Good for showing parts of a whole Can be misleading if not scaled correctly

4. Scatter Plots

Scatter plots display values for two variables for a set of data, allowing the viewer to observe relationships and correlations.

Advantages Disadvantages
Good for identifying correlations Can be difficult to interpret with large data sets
Effective for showing distribution Requires careful scaling of axes
