Introduction
Data visualization is a form of representation of various kinds of data. The term data visualization refers to the technical importance of data being represented in various forms like charts, diagrams, and pictures, which presents an overall representation of the data being manipulated through various sources.
The built-in Power BI visuals basically refer to the standard data visualization options, which are pre-dominantly implemented in the Power BI Visuals like Bar Charts, Line charts, and other variable types of charts used to represent the reports and dashboards. These limitations basically include data connectivity, data transformation, data visualization, reporting of data contents, dashboard maintenance, collaborating, and sharing of user reports, which include email, social media, and web publishing.
The custom visuals provide enhanced flexibility and customized reporting, which permits us to create tailor-made interactive visualizations that suit specific business needs.
What are Power BI Custom Visuals and Why Use Them?
What are Power BI custom visuals?
Power BI custom visuals are a set of built-in visuals that offer better visualization, like line charts, bar charts, doughnut charts, and funnel charts, which can be utilised as pre-packaged visuals for custom designs of visual representation.
How do they differ from standard visuals?
The standard visuals refer back to the pre-built chart types that originated from the platform. In contrast, custom visuals are pre-built chart types created by third-party developers, which have greater flexibility and are enhanced with a better customization option for tailor-made visualizations.
When and why to use custom visuals?
Custom visualizations are tailor-made visualization types and are meant to be unique and very specific to particular business needs with standardized built-in visuals. Since they create more impactful presentations they can be used for specialized for such needs.
Benefits of Using Custom Visuals
Enhancing data storytelling and insights: Custom visuals help in the better production of the custom visuals that implement visuals that are very attractive and aligned with data and information coupled with incorporating real-world examples so that the data storytelling is very realistic.
Creating highly interactive dashboards: Dashboards with more user engagement and interactive with added filters allow users to filter results.
Tailoring visuals to specific business needs: The selection of designs shall be performed in a cautious manner so that the designed visual elements like charts and graphs effectively communicate the key data points.
Improving user engagement and decision-making: User engagement can be improvised by focusing on the contents that are tailor-made and personalized, which provides clear hierarchical information that incorporates interactive elements that guide a greater choice of feedback, refining the design and functionality based on their needs.
Exploring the Power BI Custom Visuals Marketplace
The Microsoft App Source is a marketplace that has an online store with thousands of business applications that are built and regularly updated by industry-leading software providers for the enhancement of user experience.
The custom visuals are basically made to suit a specific need of an organization. Some noteworthy examples are the Sankey Chart, Bullet Chart, and KPI Indicators that help businesses spot trends, track performances, and make decisions.
The right custom visuals need to be selected based on various capabilities like advanced charting and geographical mapping, which are not readily available. They can be explored from the AppSource based on the comparison, trends, and relationships of the various variables that are used for the specific purpose, like Calendar head maps, which are used to display data on a calendar view, etc.
How to Import and Manage Custom Visuals in Power BI
To import a visual from Appstore
Select more visuals from the menu of visualization, which in turn connects to Appstore, and select your required visual from the displayed results.
Updating custom visuals needs access to the AppSource market place and we can find the latest version to be imported to the Power BI report.
To manage, update, and maintain the imported visuals, the user can use the Organisational visuals access to automatically update the new version, when the user selects the updated version of a visual, all reports being used by the visual get updated to the new version.
Key Considerations for Designing Custom Power BI Visuals
- Identifying visualization goals and target users: Identifying visual goals is a purpose to clearly define the various purposes for which the data visualization is used and to understand the key insights to be conveyed, pinpointing the specific audience of usage for decision-making needs.
- Ensuring performance optimization for large datasets: The key strategies that are to be implemented for performance optimization for large datasets are query optimization, data compression, indexed partitioning, etc.
- Compatibility with different Power BI environments (Desktop, Service, Mobile): Power BI has its enhanced version optimized to be compatible with Windows 10, 11, Windows Server 2015 Windows IOS, and Android IOS. The recommended processors are Intel Core i5 or higher and recommended memory of 16 GB RAM.
- Security and compliance considerations: Considering the security features, Power BI is enhanced with Row–Level Security ( RLS ), dynamic, and Azure Active Directory Security.
Core Principles for Designing Effective Custom Visuals
- Selecting the proper visual representation for data: To select the right visualization for data, basically, the key concepts are the aspect of data like the number of variables, the type of relationship, and the size of the dataset.
- Maintaining consistency with Power BI themes: Consistency can be maintained with Power BI themes by using a unified color, palette, and font type with visual elements across reports and dashboards.
- Balancing aesthetics with functionality: Balancing aesthetics can be created by an equal balance of visual appeal and practical usability, resulting in a purpose-effective product.
- Ensuring accessibility and usability for all users: Power BI ensures that a user-centered design approach includes contrasting colors, navigation options, and thorough testing of users with various kinds to identify and address potential barriers.
Advanced Custom Power BI Visuals: Real-World Use Cases
- Financial Analytics: Advanced charts for revenue tracking. The usage of Power BI aids with financial charts and graphs the simplify complex data with so many types of visuals that it can be difficult to know which best fits your needs.
- Marketing Dashboards: Heat maps and sentiment analysis. The Power BI is enhanced with the options of heat maps that are visual representations of various types of data that are gradient ally representing positive, negative, or neutral sentiments.
- Healthcare Reports: Custom visuals for patient data insights. Power BI adds potential support to health care reports by converting raw data and complex models to actionable insights to improve patient care and population management and support enhanced advanced research for a better understanding of health outcomes and treatment efficacy.
- Supply Chain Management: Interactive geographical maps. These interactive maps are another interesting aspect of Power BI as they have enhanced facilities provided to create an interactive map that connects the supply chain of any organization or as per the user’s needs.
Challenges and Limitations of Custom Visuals
- Performance trade-offs with complex visuals: The challenge, but not limited to, is that custom visuals often require proficiency in programming language and data visualization libraries, which remains a hurdle for non-technical users.
- Potential compatibility issues across Power BI versions: The compatibility issue is another factor that keeps Power BI limited by not being compatible with all data platforms or visualization tools integrated into different environments.
- Ensuring long-term maintainability of custom visuals: The challenges also extend to the factor that once if a custom visual design is not properly designed it affects the maintainability of the purpose of creation.
