Building a Real-Time Data Visualization Dashboard with Echarts and a Java Backend

1. Effect Diagram Display

The rise of data‑visualization large screens has sparked a wave of interest, with many business owners eager to build their own impressive dashboard cockpits.

1.1 Dynamic Real‑Time Data Effect Diagram

1.2 Right‑Click Theme Switching

2. Requirement Specification

2.1 Determine Screen LED Resolution for Product Deployment

This case uses a 16:9 aspect ratio with full‑screen display (F11).

2.2 Deployment Method

Based on a portable executable program that runs on Windows, Linux, macOS and other operating systems; simply copy the program to the server without additional environment dependencies.

Viewing options: run the program directly on the server or open it remotely via a browser such as Chrome or 360.

3. Overall Architecture Design

Front end built with the open‑source Echarts library, edited in WebStorm.

Back end implemented with Java Web, edited in IntelliJ IDEA.

Data transmission format: JSON.

Data source: initially JSON files; adding MyBatis enables PostgreSQL, MySQL, Oracle, SQL Server, SQLite; adding POI supports Excel; HTTP API can also be customized.

Data update: HTTP GET polling; real‑time push via backend monitoring can be used in production.
