随着信息技术的快速发展，图形编程在教育领域的应用越来越广泛。Logo语言作为一种图形编程语言，以其直观、易学、有趣的特点，深受广大编程爱好者的喜爱。本文旨在探讨如何利用Logo语言绘制天气图标，通过实践案例展示Logo语言在图形编程领域的应用。
二、Logo语言简介
Logo语言是一种图形编程语言，由美国麻省理工学院教授西摩·帕普特（Seymour Papert）于1967年发明。它以turtle图形作为编程对象，通过移动turtle绘制图形。Logo语言具有以下特点：
1. 简洁的语法：Logo语言的语法简单，易于学习和使用。
2. 直观的图形操作：通过移动turtle绘制图形，直观易懂。
3. 强大的图形库：Logo语言提供了丰富的图形库，可以绘制各种图形。
4. 丰富的编程功能：Logo语言支持循环、条件判断等编程功能，可以实现复杂的图形绘制。
三、天气图标绘制分析
天气图标是日常生活中常见的图形，具有以下特点：
1. 简洁明了：天气图标需要直观地表达天气状况，因此图形要简洁明了。
2. 形象生动：天气图标需要形象生动，便于人们识别。
3. 个性化设计：根据不同的需求，可以设计具有个性化的天气图标。
四、Logo语言绘制天气图标实践
以下以绘制晴天、多云、雨天、雪天四种天气图标为例，展示Logo语言在绘制天气图标中的应用。
1. 晴天图标
