Recently I have been working on an open source data visualization tool called DataEase. According to the official introduction of the project, DataEase is an open source data visualization analysis tool available to everyone, which can help users quickly analyze business data and gain insight into its trends, providing support for business improvement and optimization of enterprises. DataEase supports rich data source connections, can quickly create charts by dragging and dropping, and can easily share with others.
As a technical engineer, I have been researching issues related to architecture and deployment, and I have published several blog posts about DataEase before. Recently, the company's operational cockpit dashboard was completed with DataEase, and today I will show the effect.
Large screen effect
Note: The name of the big screen was changed to obscure the real company information.
And the effect on the mobile phone is as follows:
The specific content displayed on the large screen of the dashboard
■ The total revenue of the company's three types of revenue can be dynamically obtained through the text box to calculate the total revenue value;
■ The national map can display the status of each region, and show the level of revenue through different colors;
■ Display the proportion of revenue of each region and province through two circular charts, and drill-down operations can be performed in both regions and provinces;
■ Display the distribution area of key customers through the word cloud map, and the size of the word map can be displayed according to the level of the value;
■ Real-time display of transaction amount and KPI completion. Since the method of direct connection to the database is adopted here, the value can be displayed in real time.
detailed operation
The ring graph in the middle of the dashboard is configured with linkage effects. Click on the specified province to view the data corresponding to the province in other views.
Using the drill-down function, click on the area in the donut chart on the left to switch to the area and display the data of the provinces in the area. Clicking on a specific province in the map can also display the data of the cities in that province on the map;
Finally, a large-scale linkage effect was made. Click the "East China" region in the donut chart on the left, and other views can be changed to display the data of the East China region.
Data Sources
This dashboard connects to the MySQL database of the operation platform, directly connects to the database, and obtains data through SQL of multi-table joint query. Of course, DataEase can also periodically extract data and save it to Doris, which will have higher performance. But I personally think that the timeliness of direct connection is more important.
Due to the sensitive data involved, the specific data displayed on the large screen above has been modified by individuals.
Use summary
First of all, I really appreciate that DataEase adopts an open source software delivery method, which allows users to download and use it conveniently. DataEase also has a very active technical community. Some of the needs I mentioned in the community have been recorded. Community members attach great importance to user feedback. Thumbs up for this serious product team!
Second, the operating experience of the software is very good. The whole process of making a dashboard can be divided into three steps: establishing a data source, creating a data set, and making a dashboard. The method is simple and clear, and after the large frame is completed, the details can be further beautified. For example, graphics display data, view boxes, background settings for the entire dashboard, etc. Through the relatively simple operation interface of DataEase, we can also create cool dashboards.
Third, this is a rapidly evolving software tool. As a rising star in BI tools, DataEase adopts the rhythm of monthly update iterations, which means that new versions will be released every month to update some functions. My personal feeling is that this software has been improving rapidly. The dashboard made above also incorporates some of the latest features of the DataEase project released in March. Looking forward to waiting until next month to release new features, I can optimize my dashboard.
