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

1. Effect Diagram Display

1. Dynamic real‑time data effect diagram

2. Right‑click to switch theme

2. Requirement Planning

1. Determine screen LED resolution for product deployment

Based on a 16:9 aspect ratio, full‑screen display with F11.

2. Deployment method

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

Viewing method: can be viewed directly on the server or 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: currently a JSON file; MyBatis can be added to support PostgreSQL, MySQL, Oracle, SQL Server, SQLite; POI can be added for Excel; HTTP API can be customized.

Data update method: HTTP GET polling; real‑time push can be implemented by monitoring back‑end data.
