Data Visualization Dashboard Project: Architecture, Configuration, and Code Overview

1. Effect Diagram Display

1.1 Dynamic real‑time data effect diagram

Illustrates a live‑updating data screen that refreshes in real time, creating a visually striking dashboard.

1.2 Right‑click theme switching

Shows how users can switch visual themes via a right‑click context menu.

2. Requirement Specification

2.1 Screen resolution for deployment

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

2.2 Deployment method

The solution is packaged as a portable executable that runs on Windows, Linux, or macOS without additional dependencies; the program can be launched directly on the server or accessed remotely through any modern browser (e.g., Chrome, 360 Browser).

3. Overall Architecture Design

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

Back end implemented in Java Web, developed in IntelliJ IDEA.

Data exchange format: JSON.

Data source: initially a local JSON file; can be extended with MyBatis to support PostgreSQL, MySQL, Oracle, SQL Server, SQLite, or with POI for Excel, and can also consume HTTP APIs.

Data update mechanism: HTTP GET polling; alternatively, real‑time push from the back end can be used.
