1. Introduction and background

In business management and decision-making, a large number of reports need to be effectively processed and analyzed to release the value of data. However, the data of each department is too complex, making it difficult to complete comprehensive analysis of multi-section, multi-modal data and indicators, which is not conducive to efficient business decision-making. Data visualization, as an important topic in the current scientific and technological field, is particularly critical in this context. By converting complex data sets into graphical interfaces, making intuitive representations while revealing patterns, trends, and connections behind the data is critical to understanding the problem you are working on.

Huawei Cloud Astro Canvas (i.e., visual large-screen application development) is a development tool platform specially designed for large-screen display. It provides a component library that can be flexibly combined to meet the visual large-screen needs of various industries. Due to its ease of use and comprehensive functions, it has been widely used in finance, education, energy and other fields.

However, there has not been much in-depth research on how this tool can help auditors perform effective data analysis and integration. Therefore, the Huawei Cloud Astro team believes that it is necessary to improve this gap: understand the company's internal data flow and make reasonable suggestions for business decisions, making Astro Canvas an increasingly important research object.

2. Overview of Huawei Cloud Astro Canvas

Huawei Cloud Astro Canvas is one of the sub-services of Huawei Cloud Astro Platform low-code flagship camp. It is a tool platform developed for enterprise-level large-screen displays. This tool uses advanced data visualization technology, provides cool visual element templates and arrangement customization options, elegantly meets complex business scenario applications, and provides enterprises with in-depth data analysis and decision-making support.

The Astro Canvas core can be roughly divided into two parts: first, the back-end data processing system, which is mainly responsible for collecting, processing, and sorting data incoming from different sources (such as databases or third-party APIs) on the server; second, the front-end display system, It includes a drawing engine and interaction module, which converts background-processed data into intuitive and easy-to-read images and displays them on the screen.

One of the features of Astro Canvas is its component library that includes industry-specific features. The component library contains a variety of common business charts and elements, such as line charts, pie charts, column charts, radar charts, etc., and each type offers numerous customization options. This means that no matter what style of page is built, users can almost always find a suitable solution on Astro Canvas, saving time and energy in interface design during the development process.

The second is user-friendly interaction design. Astro Canvas utilizes a highly encapsulated operating process, allowing users to use the mouse to drag graphic components to create applications, greatly reducing programming difficulty and shortening the development cycle. In addition to basic canvas editing, Astro Canvas also has functions such as data filtering, sorting, and detailed information viewing. At the same time, a special permission management mechanism is built in to allow users to easily define who has the right to view or modify page content.

Astro Canvas has successfully helped various fields visualize complex data, such as: real-time monitoring of transaction changes in the financial industry, statistical analysis of student performance and rankings in the education sector, and tracking and querying of user views and retention rates in the technology industry. With practice, Astro Canvas clearly depicts the stories behind massive data and fully demonstrates its functionality and effectiveness. It is loved by enterprises and has become an indispensable tool for visual large-screen development.

3. Successful Practice

1. Practical application in the education industry

The "Software Major Student Training Base" uses Astro Canvas to develop a visual big data analysis system that integrates student data and graphically displays key indicators such as average scores and passing rates for each department, grade to class. The person in charge can intuitively understand the effect of teaching activities through this system and adjust the link design. In addition, Astro Canvas is used to connect Welink to synchronize more than 4,000 teachers and students at the school, create a "student portrait" function, and extract individual student information, such as foul records, physical test scores, club participation, etc. Astro Canvas uses data to deconstruct phenomena and collaborates with teachers to teach students in accordance with their aptitude.

2. Practical application in the financial industry

The bank uses Astro Canvas to establish a comprehensive risk management platform, including a credit risk assessment module, which can intelligently analyze loan applicants' historical repayment records, assets, work income and other information to accurately predict their default probability. Another example is the portfolio optimization module, which converts important indices such as the return rate, volatility, and Sharpe ratio of the portfolio into visual graphics. By adjusting the parameters, you can instantly view the result feedback for decision-makers to consider the best strategy.

3. Practical application in transportation industry

The airport adopted the Astro Canvas service to build a nationwide network status monitoring center. The center maps the working status of airport infrastructure, wired communication facilities and client access points onto a real-time virtual map. When an abnormality occurs somewhere, it will be displayed in color according to geographical location. Technicians can immediately locate the source of the problem and obtain details by clicking on it.

The above practices are a true reflection of Astro Canvas' ability to effectively understand complex data and tailor-made solutions for specific business scenarios. You can see the huge potential of this tool in handling complex data visualization tasks. Astro Canvas is changing the modern work model.

4. Development Guidelines and Best Practices

1. Tool experience

When starting to use Astro Canvas to develop large screens, it is recommended to experience its built-in sample project templates first. These templates cover common scenarios, and each default chart can display and edit the corresponding parameter settings. Through this, developers can quickly become familiar with the operating procedures and various functions.

2. Demand planning

Make detailed requirements planning before starting development. Factors such as how to arrange the page layout, which graphics to choose to present data, and how to configure interactive events need to be considered. Preliminary planning can effectively avoid the extra time spent on frequent adjustments to the plan later.

3. Data organization

Astro Canvas supports reading and processing data directly from databases, APIs or files. Ensuring that the source data is properly organized, such as classifying by fields and sorting in a certain order, will make subsequent processing smoother.

4. Use modular design thinking

Astro Canvas provides many preset components and adopts a modular design, so more complex problems can be simplified and small components can be tested and optimized one by one. After creating a custom template, you can save it for reuse.

5. Utilize permission management system

In addition to basic display and editing functions, Astro Canvas also includes a complete permission control mechanism. Conditionally exposing or hiding specific information can better meet the needs of enterprise-level applications.

6. Color and text selection

Appropriate color matching that matches the theme enhances the viewer's visual enjoyment, while clear and understandable fonts and labels help convey in-depth and understandable insights. Remember to use appropriate decorative elements to reduce reading load.

7. More testing, more feedback

Continuously trying new methods, obtaining user feedback, and making iterative updates based on feedback can provide the best experience for the product.

In summary, the key steps for developing Huawei Cloud Astro Canvas are summarized: mastering the basics, clarifying goals, building data, module design, permission control, and aesthetic appreciation are the only ways to use Astro Canvas easily and freely.
