Chart Evolution: Comprehensively Exploring Bar, Line, Area, and More: Infographic Round-Up of Data Visualization Techniques

In the realm of data visualization, infographics have become an indispensable tool for conveying complex information in a digestible, visually appealing manner. Over the years, different types of charts have emerged, each serving specific purposes and providing insight into various datasets. This article comprehensively explores the evolution of key chart types by focusing on bar, line, area, and other popular visualizations, with a round-up of various infographic resources that showcase these techniques in action.

### Bar Charts

Bar charts are among the oldest and most widely used chart types, offering a clear comparison of discrete variables. They typically feature vertical or horizontal bars that represent data points, with the length or height of the bars indicating the value.

The evolution of bar charts has seen them adapt to a range of different styles. Infographic resources, such as The InformationLab’s “Comparing Bar Charts,” provide a detailed comparison of various bar chart designs, helping readers make informed decisions about when and how to use them.

### Line Charts

Line charts are another classic chart type that uses lines to connect sets of data points, showing the relationship between them over time or space. They are particularly useful for illustrating trends and fluctuations in continuous data.

“Timeline of World History” by Timeline Center is a prime example of an infographic that makes use of line charts to highlight significant historical events and their timelines. This resource demonstrates how line charts can not only convey data but also tell a story.

### Area Charts

Area charts are similar to line charts, but with one fundamental difference: they come with filled-in areas that represent the extent of data. This additional visual cue can help viewers grasp the total magnitude of data points, especially when comparing them to other variables.

CNN’s “Economic Recovery Efforts” is a compelling example of area charts in action. The infographic illustrates the gradual increase in economic growth over time by filling in the color between the line charts’ data points.

### Pie Charts

Although controversial regarding clarity and efficiency, pie charts are a familiar sight for most people. They depict fractions of a whole with slices of a circle, with the size of each slice corresponding to the proportion of the total.

Infographics like The New York Times’ “America’s Health Care Spending — By the Numbers” show how pie charts can be utilized to convey large amounts of data while maintaining a visually appealing format.

### Scatter Plots

Scatter plots, also known as XY plots, represent data points on a coordinate plane. The data is encoded by symbols – usually circles or points – and can be used to look at quantitative relationships between two variables.

The infographic “Global Population Growth” by Statista is a great example of scatter plots being used to illustrate how demographic shifts manifest on a global scale.
