Best Data Visualization Projects for Beginners

Data visualization is an important component of the entire data science workflow. It is the data display, including chart design, dynamic combination, two-dimensional charts, three-dimensional charts, linkage, drilling, large-screen display, etc.

With the appropriate visualizations, a data scientist can understand the structure of the data they have, identify potential issues, craft analytical strategies, and summarize their results for others. Here are a few data visualization examples and project ideas that you, as a beginner, can execute to get better at the art of data visualization.

1. Fundamental Charts

Before you start with any project, you need to learn how to quickly make the fundamental charts. Charts like scatter plots, histograms, bar charts, box plots, heat maps, correlations, etc., can be made easily.

You can use any small dataset from an external resource to practice most of these fundamental charts. In case you’re using Python, you’ll find a few built-in datasets that you can use.

2. Time-Series Plot

Get a good time-series dataset like Tesla and Apple stock prices, Ozone level detection, or literacy rates over time. You can use these datasets to create a time-series plot.

Time-series are problems where a numeric or categorical value must be predicted, but the rows of data are ordered by time.

In simple words, a time-series plot is just a line graph, but you have to pay special attention to the dates on the X-axis, especially when your chart contains multiple lines with different start and end times. Also make sure your Y-axis has the correct units, and that both your lines are in the same units.

3. Map Charts

You can use a map chart to compare values and show categories across geographical regions. Use it when you have geographical regions in your data, like countries/regions, states, counties, or postal codes.

Being able to make attractive data maps is a huge bonus. Check out some project ideas that you can try out.

4. Word Clouds

A word cloud is a collection, or cluster, of words depicted in different sizes. The bigger and bolder the word appears, the more often it’s mentioned within a given text and the more important it is.

Also known as tag clouds or text clouds, these are ideal ways to pull out the most pertinent parts of textual data, from blog posts to databases. Word Clouds can also help business users compare and contrast two different pieces of text to find the wording similarities between the two.

Things To Keep In Mind

• Employ simplicity: Simplicity is the key to creating effective data visualizations. You should focus on using simple charts that are easy to digest.
• Display only the most important information: When you’re new to charting, you may want to put in a lot of information so that you don’t leave out anything of value. Resist this urge, because people can take in only so much information before their eyes glaze over.
• Require little explanation: Don’t make things so complicated that your users require a manual to understand what you’re trying to convey.
• Don’t overload your data: It’s important to avoid overloading your data visualization.
• Stay away from 3-D: It’s recommended that you avoid this type of chart until you get more experience under your belt.
