이 가이드에서는 Google 시각화 데이터 소스 라이브러리를 사용하여 데이터 소스를 구현하는 방법을 설명합니다.
이 가이드에서는 소개의 개념 다음에 나오는 시작하기 튜토리얼 섹션을 제공합니다.
이 접근 방식을 사용하면 간단한 데이터 소스를 만들고 시각화를 사용하여 테스트할 수 있습니다. 다른 가이드 섹션은 외부 데이터 저장소 사용과 기능 및 이벤트 흐름 정의로, 좀 더 복잡한 구현을 다룹니다. 요구사항에 따라 세 튜토리얼을 모두 완료할 필요는 없지만 최소한 시작하기 섹션은 완료하는 것이 좋습니다.
가이드의 다른 섹션은 지식을 쌓는 데 도움이 됩니다.

The other tutorial sections are [Using\nan External Data Store](/chart/interactive/docs/dev/dsl_csv) and [Defining\nCapabilities and the Flow of Events](/chart/interactive/docs/dev/dsl_httpservlet), which cover more complex\nimplementations. Depending on your requirements, you might not need to\ncomplete all three tutorials, though it is recommended that you at least\ncomplete the [Getting Started](/chart/interactive/docs/dev/dsl_get_started) section.\nThe other sections of the guide help you to build on your knowledge.\n\nContents\n--------\n\n- [Audience](#audience)\n- [Guide Overview](#overview)\n- [Examples Quick Reference](#quick)\n- [More Information](#more)\n\nAudience\n--------\n\nYou need to be familiar with [Java](http://www.java.com/) and [Java\nservlet technology](http://java.sun.com/products/servlet/overview.html) to use the library.\n\nYou also need to understand [how to\nuse charts](/chart/interactive/docs), and though not essential, it is helpful to be familiar\nwith the Google Visualization API [wire\nprotocol](/chart/interactive/docs/dev/implementing_data_source#requestformat), and the [query\nlanguage](/chart/interactive/docs/querylanguage).\n\nGuide Overview\n--------------\n\nThis guide contains the following sections:\n\n- [Introduction](/chart/interactive/docs/dev/dsl_intro)\n\n\n Introduces the library, providing an overview of how a data source\n works.\n- [Installation](/chart/interactive/docs/dev/dsl_install)\n\n\n Describes the library's prerequisites and dependencies, and how to download\n and build the source code.\n- [Getting Started](/chart/interactive/docs/dev/dsl_get_started)\n\n Introduces `SimpleExampleServlet`. `SimpleExampleServlet` is\n the simplest example implementation that is provided with the library.\n This section also provides step-by-step instructions on how to run and\n test `SimpleExampleServlet`.\n- [Using an External Data Store](/chart/interactive/docs/dev/dsl_csv)\n\n Introduces `CsvDataSourceServlet`. `CsvDataSourceServlet` is\n an example implementation that uses a CSV file as an external data store.\n This section also provides step-by-step instructions on how to run and\n test `CsvDataSourceServlet`.\n- [Defining Capabilities and the Flow of Events](/chart/interactive/docs/dev/dsl_httpservlet)\n\n Introduces `AdvancedExampleServlet2`. `AdvancedExampleServlet2` is\n an example implementation that defines capabilities and flow\n of events. This section also provides step-by-step instructions on how\n to run and test `AdvancedExampleServlet2`.\n- [Handling Security, Errors, Warnings,\n and Logging](/chart/interactive/docs/dev/dsl_errors_and_logging)\n\n Describes how to make your data source secure,\n and how to handle errors, warnings, and logging.\n- [Implementation Tips](/chart/interactive/docs/dev/dsl_key_concepts)\n\n Provides information that will help you write more complex implementations\n of the library.\n- [Library\n Packages and Key Classes](/chart/interactive/docs/dev/dsl_packages)\n\n Provides a high level introduction to the library's packages and key\n classes.\n\nExamples Quick Reference\n------------------------\n\nThe library is provided with six example implementations. Three of these\nare described in this Guide, the others are not. The following\ntable will help\nyou find an example of the type of behavior you want to implement.\n\n|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------|------------------|--------------------|--------------------|\n| **Example** | **Servlet extended** | **Capabilities** | **Flow of events** | **Source of data** |\n| [`SimpleExampleServlet`](http://code.google.com/p/google-visualization-java/source/browse/trunk/examples/src/java/SimpleExampleServlet.java) Described in [Getting Started](/chart/interactive/docs/dev/dsl_get_started) | `DataSourceServlet` | `NONE` | Default | Within class |\n| [CsvDataSourceServlet](http://code.google.com/p/google-visualization-java/source/browse/trunk/examples/src/java/CsvDataSourceServlet.java) Described in [Using an External Data Store](/chart/interactive/docs/dev/dsl_csv) | `DataSourceServlet` | `NONE` | Default | CSV file |\n| [`AdvancedExampleServlet2`](http://code.google.com/p/google-visualization-java/source/browse/trunk/examples/src/java/AdvancedExampleServlet2.java) Described in [Defining Capabilities and the Flow of Events](/chart/interactive/docs/dev/dsl_httpservlet) | `HttpServlet` | `SELECT` | Custom | Within class |\n| [SimpleExampleServlet2](http://code.google.com/p/google-visualization-java/source/browse/trunk/examples/src/java/SimpleExampleServlet2.java) Not described in this Guide | `HttpServlet` ` ` | `NONE` | Custom | Within class |\n| [AdvancedExampleServlet](http://code.google.com/p/google-visualization-java/source/browse/trunk/examples/src/java/AdvancedExampleServlet.java) Not described in this Guide | `DataSourceServlet` | `SELECT` | Default | Within class |\n| [SqlDataSourceServlet](http://code.google.com/p/google-visualization-java/source/browse/trunk/examples/src/java/SqlDataSourceServlet.java) Not described in this Guide | `DataSourceServlet` | `SQL` | Default | SQL database |\n\nMore Information\n----------------\n\nFor information on the Data Source Library project, see the [home\npage](http://code.google.com/p/google-visualization-java/)."]]
