Top 7 Examples of Effective Data Visualization
Data visualization is an essential tool for businesses to understand and communicate insights from their data effectively. Visualization can help businesses gain an understanding of the data they collect, enabling better decision-making, and help communicate complex ideas simply. In this article, we will explore seven examples of data visualization and its importance in data analysis, including some industry-specific examples and tips for creating effective visualizations.
Types of Data Visualization
There are a lot of different ways to represent data visually, but here are some of the most common types of data visualizations:
Charts
Charts are the most commonly used type of visualization, and they come in many shapes and sizes. Some popular chart types include bar charts, line charts, pie charts, and scatter plots.
Graphs
Graphs are graphical representations of data with lines or curves connecting data points. Graph types include line graphs, scatter graphs, and area graphs.
Maps
Maps are geographical representations of data, often used to show location data or regional data points.
Dashboards
Dashboards are a graphical user interface that display the most important information, metrics and data on a single screen. Interactive dashboards let users drill-down to explore the data further.
Infographics
Infographics are highly visual representations of data and information that typically include text, numbers, and images to help convey complex information in a way that is easy to understand.
Heatmaps
Heatmaps use color-coding to help visualize data intensity. Heatmap charts are a helpful way to visualize large data sets and highlight trends.
Tree Maps
Tree maps make it easy to visualize data in hierarchical form, breaking down a large dataset into smaller subsets using rectangles that are sized proportional to the data value.
Importance of Data Visualization in Data Analysis
Data visualization statistics show that businesses that use visualization tools are making better decisions and more informed choices. Visualization helps to convert complex data sets into meaningful patterns, aiding data analysts to recognize trends, draw insights and communicate their findings to stakeholders. After all, complex data sets can't be understood easily or communicated in a way that non-technical users can understand.
For instance, business intelligence analysts use data visualization to uncover insights in large amounts of data generated by a business's processes. Marketers use data visualization to identify what campaigns are driving traffic to a website, and where the visitors are coming from.
So, to transform your data into actionable insights, data visualization is key. By presenting data in easily consumable, visually-appealing formats, data becomes more accessible to all users and can be harnessed as a business asset.
7 Examples of Data Visualization
1. Covid Tracker Dashboards
The COVID-19 pandemic sparked an unprecedented spike in data visualizations, while businesses, government agencies, and organizations sought to inform citizens and employees about the spread of the virus. Dashboards tracking this information in real-time became widespread. The interactive COVID-19 Tracker dashboard by Johns Hopkins University showcased the spread of the virus worldwide using a world map and other charts. The dashboard made it simple to see affected locations, infection rates, deaths, and the number of recoveries.
2. NFL's NextGen Stats
The NFL's NextGen statistics site is a great example of how data visualization can be a useful way of providing insights into game strategy. The platform offers ultra-precise tracking of every move on the field, using data obtained from RFID beacons mounted in player spandex. This paints an actual picture of players and their movements on the field using visualizations.
3. Spotify Wrapped
Spotify Wrapped provides users with a fun way to summarize their year's musical history, giving them insights on the artists they listened to the most, the styles of music they enjoyed, and how these tastes compared with others worldwide.
4. Risk Atlas
Risk Atlas data visualization tool of the World Bank provides visualization of various risk factors, including natural disasters, pandemics, and global economic indicators. Risk Atlas provides insights that allow policymakers to track their country's vulnerabilities to risks and effictively plan how to mitigate them, as well as preparing for their impact.
5. Flight Tracker
A tool that uses a map to show flights in real-time is an excellent example of how data visualization can lend context for significant amounts of data. Flight tracking services such as Flightaware utilizes data from airline networks to showcase flight traffic in real-time, letting air traffic controllers and passengers know which planes are active at any one time.
6. Google Trends
Google trends is an invaluable tool for trend analysis that offers insights into the popularity of search terms worldwide. Through interactive maps and charts, users can see the popularity of search phrases across different regions, compare popularity over time, and the rising and falling popularity of associated phrases.
7. Gapminder
Gapminder is a global data visualization resource that aims to put data on a global level, making it accessible to anyone. It encourages educators and journalists to incorporate data analysis and visualization into their work, with interactive data visualizations for a wide range of data sets covering many aspects of global public health and economics.
How to Create Effective Data Visualizations
Creating data visualizations that communicate insights to your audience can be challenging, but following these best practices can help:
- Keep it simple. Visualization should never get in the way of the data. Strive for clear, easy-to-understand visualizations.
- Know your audience. Understanding your audience's demands and preferences is crucial to designing visualizations that speak to them.
- Encourage exploration. Keeping visualizations interactive helps users explore and discover insights that may not be visible in a static view.
- Avoid clutter and distractions. A cluttered visualization might make a handsome graphic. However, with multiple colors, fonts, and elements, it can detract from your content's core message.
- Keep it consistent. Use a consistent style and color scheme to maintain the coherence of your visualizations.
Conclusion
Now that we have seen some of the coolest data visualizations, it is easy to see how important and useful data visualization is to business and data analysts. Visualization helps businesses make informed decisions and communicate insights to a diverse audience - from non-technical stakeholders to subject matter experts. By following visualization best practices, data analysts can design effective and engaging visualizations that provide new perspectives and insights. Harness the power of visualization for your business today, and reap the rewards of informed decisions.
