Healthcare: Real-time data visualization is used in healthcare to monitor patient data, such as heart rate, blood pressure, and oxygen levels. This enables healthcare professionals to identify and respond to emergencies quickly.

Internet of Things (IoT): Visualizing real-time IoT data enables engineers to monitor and control connected devices in real time. It enables businesses to optimize operations, reduce downtime, and improve safety.

Manufacturing: Visualizing real-time data in manufacturing allows you to monitor production lines and identify quality issues in real time. It enables manufacturers to improve product quality and reduce downtime. 

Transportation: Here, real-time data visualization enables you to monitor traffic patterns, weather conditions, and vehicle performance in real time. It also enables transportation companies to optimize routes, reduce fuel consumption, and improve safety.

The benefits of visualizing real-time data are so enormous that they cannot fit on a plate—It enables businesses to make informed decisions quickly, identify errors and anomalies as they occur, and improve decision outcomes. 

However, to get the most out of real-time data visualization, you have to follow some best practices. They not only expedite the entire process but also make it enjoyable. So, the next section takes you through the best practices for real-time data visualization. 

Best practices for real-time data visualization

The following best practices ensure that you stay ahead of the competition and achieve greater success while visualizing real-time data. They are not just best practices but also key best practices: 

Preparing and cleaning data: Before visualizing real-time data, you must ensure that the data is clean, accurate, and well-structured. These can demand you carry out data cleansing, normalization, and transformation, among other things.

Designing effective visualizations: You must ensure that visualization is effective—that is, it should be clear, concise, and easy to interpret. Your visualizations should also be tailored to the audience and the specific use case.

Ensuring data security and privacy: While you are visualizing real-time data, you should know that it might involve working with sensitive data that may be subject to privacy regulations. So, you must ensure that data security and privacy are taken into account at all stages of the process.

Choosing the right visualization tool: There are several real-time data visualization tools available, each with its own strengths and weaknesses. The next chapter will empower you with information on how to choose a tool that fits your specific needs and requirements, as this is important.

Real-time data visualization tools

As I mentioned earlier, there are several real-time data visualization tools available to you. Each has its own strengths and weaknesses. The following are some of the popular data visualization tools that update in real-time:

Apache Kafka: Apache Kafka is a distributed streaming platform that allows you to process real-time data. Though it doesn’t provide specific data visualization tools, it provides you with a high-throughput, low-latency platform for processing streaming data, which you can use to build your own real-time data visualizations.

Tableau: Tableau is a user-friendly data visualization tool that supports real-time data processing and visualization. It allows you to connect to a wide range of data sources and create interactive visualizations in real time.

Grafana: Grafana is an open-source data visualization and monitoring tool that you can use for real-time data processing and visualization. It allows you to create interactive dashboards and alerts based on real-time data.

Kibana: Kibana is an open-source data visualization tool, which you can also use to process and visualize real-time data, and create custom dashboards and alerts.

Microsoft Power BI: Microsoft Power BI is a cloud-based business analytics service that supports real-time data processing and visualization. It allows you to create interactive dashboards and reports that can be shared with others.
