Technology Stack:
ECharts is built using web technologies such as HTML5, CSS, and JavaScript. It leverages the capabilities of modern browsers to render and interact with charts. The project uses the popular JavaScript library, jQuery, for DOM manipulation and event handling.
ECharts also incorporates several open-source libraries and frameworks to enhance its functionality. For example, it utilizes Apache's PivotTable.js for pivot chart support and Leaflet.js for geographic map integration. These libraries provide additional features and extend the capabilities of ECharts.
The choice of web technologies and libraries in ECharts enables cross-platform compatibility and ensures that charts can be easily integrated into existing web applications.
Project Structure and Architecture:
ECharts follows a modular and extensible architecture that allows for easy customization and scalability. The project is organized into different components, including the core charting library, modules for specific chart types, themes for styling, and plugins for additional features.
The core charting library provides the foundation for creating and rendering charts. It handles the data processing, rendering logic, and user interactions. Each chart type module builds upon the core library, adding specific functionalities and visualizations.
ECharts also follows the Model-View-Controller (MVC) design pattern, separating data modeling, chart rendering, and user interactions. This architectural pattern promotes code maintainability and reusability.
