In today’s digital age, we are swamped with data that can be overwhelming and difficult to interpret. This is where data visualization comes into play.
Data visualization is the graphical representation of data and information that helps people better understand and interpret complex data sets.
Microsoft Power BI is one of the many data visualization tools available on the market. It is designed to turn insights into visuals, making it easier for individuals to make sense of complex data.
In this article, we will explore why data visualization matters and how data visualization tools like Microsoft Power BI can improve data presentation.
Definition of Data Visualization
Data visualization is the use of common illustrations, such as charts, plots, infographics, and animations, to represent data. These visualizations simplify the communication of complex data relationships and insights, making it easier to understand the information.
Data visualization tools allow you to turn granular data into visually appealing and easy-to-understand business information.
By accessing external data sources, these tools not only improve the clarity of your Key Performance Indicators (KPIs), but they also bring data together and use AI-driven analytics to reveal relationships between your KPIs, the market, and the rest of the world.
Benefits of Data Visualization
Your data holds valuable insights that can drive your business forward. However, it can be difficult to make sense of the raw data alone. When you view your data in a visual format, patterns, connections, and other “a-ha” moments that would otherwise be hidden become apparent.
Data visualization brings data to life, allowing you to tell the story of the insights within your numbers. With live data dashboards, interactive reports, charts, and graphs, as well as other visual representations, data visualization enables users to quickly and effectively develop insightful business insights.
How It Works?
1. Idea Generation:
Data visualization is often used to stimulate team-wide ideation. They are frequently used during brainstorming or Design Thinking sessions at the start of a project to gather diverse perspectives and highlight common concerns.
Even though these visualizations are typically rough and unrefined, they help lay the foundation for the project and ensure that the team is aligned on the problem they want to solve for key stakeholders.
2. Idea Illustration:
Data visualization for idea illustration helps to communicate an idea, such as a strategy or procedure. It is frequently used in learning environments, such as tutorials, certification courses, and centers of excellence, but it can also be used to represent organizational structures or processes, facilitating communication between individuals responsible for specific tasks.
Project managers often use Gantt charts and waterfall charts to depict workflows, while data modeling uses abstraction to represent and better understand data flow within an enterprise’s information system, allowing developers, business analysts, data architects, and others to better understand the relationships in a database or data warehouse.
3. Tracking Trends Over Time:
Once a baseline has been established, trends will begin to emerge. Track progress, identify trends, and use your insights to make strategic, informed decisions.
As you build your trends, changes in patterns indicate if things go off course, allowing you to respond quickly to any sign of degraded performance.
Types of Data Visualizations
- Tables are rows and columns used for comparing variables. While they can display a large amount of data in a structured manner, they can also confuse users who are only interested in high-level trends.
- Pie charts, on the other hand, divide data into sections that represent portions of the whole and provide a straightforward way to organize and compare data. Pie charts clearly illustrate the proportion of each value to the whole, making them more understandable than simply listing percentages that sum up to 100%.
- Line charts and area charts are frequently used in predictive analytics to show the evolution of one or more quantities over time. Area charts connect data points with line segments, layering variables on top of one another and using color to differentiate between variables. Line graphs, on the other hand, use lines to demonstrate these changes. Line charts are widely used for various business purposes because they quickly and concisely illustrate overall trends in a manner that is difficult to misinterpret. They are especially useful for comparing trends across multiple categories over the same time period, such as sales by age group for three distinct product lines.
- Histograms are bar graphs that represent the quantity of data within a specific range. This type of visual representation makes it easier to identify anomalies within a given dataset.
- Scatterplots and bubble charts are used to reveal the relationship between two variables and are often used in regression data analysis. However, they can sometimes be confused with bubble charts, which are used to visualize three variables using the x-axis, the y-axis, and the size of the bubble.
- Heat maps are graphical representations that are useful for visualizing location-based behavioural data, such as on a map or website.
- Tree maps, which display hierarchical data as a collection of nested shapes, typically rectangles, are a visual representation of tree structures. They are ideal for comparing proportions between categories based on the extent of their respective areas.
Data Visualization Tools
Data visualization tools have never been more accessible. Open-source libraries, such as D3.js, enable analysts to present data interactively and engage a larger audience with new information. Some of the most prominent open-source visualization libraries include:
- Echarts, a robust charting and visualization library that makes it easy to add intuitive, interactive, and highly customizable charts.
- Vega, which characterizes itself as a “visualization grammar” and provides support for customizing visualizations across large web-accessible datasets.
- deck.gl, a framework for exploratory data analysis on large datasets and a component of Uber’s suite of open-source visualization frameworks.
Visualizing Data Using Microsoft Power BI
Power BI allows for the analysis and exploration of data both on-premises and in the cloud. It provides the ability to collaborate and securely share interactive dashboards and reports with colleagues and organizations.
Power BI consists of several components that can be sold separately and used independently.
Benefits of Using Microsoft Power BI
Power BI offers several advantages over existing analytical tools, including:
- A cloud-based and desktop interface
- Features such as data warehousing, data discovery, and interactive dashboards
- The ability to import custom visuals
- Scalability throughout the entire organization
Desktop Microsoft Power BI
Power BI is a free, system-installable application that can be downloaded and deployed and is compatible with multiple data sources. An analysis typically begins in Power BI Desktop, where reports are created and then published to the Power BI service, where they can be shared with the Power BI Mobile applications for viewing on mobile devices.
Installation and Setup
There are three ways to install Power BI:
- Launch the Microsoft Store, search for “Power BI,” and select “Get” to install.
- Visit the Power BI Desktop download page and select the “Free Download” option.
- Download Power BI Desktop for free from the Power BI service website by logging in and selecting the download button in the upper-right corner.
- After installing Power BI Desktop, you can visit the Power BI service website and sign in. If you haven’t registered yet, you can use your school or work email address to register for free.
All in all
Data visualization tools such as Microsoft Power BI are essential for transforming complex data sets into understandable representations. Through data visualization, we can uncover insights that would otherwise be hidden in the data.
Microsoft Power BI provides a user-friendly platform for individuals and businesses to create beautiful, informative, and easy-to-understand data visualizations.
With the growing importance of data in today’s world, it is important to recognize the value of data visualization and its role in improving data presentation.
