可视化大作业基本功能图
2016-12-14 01:17:36 0 举报可视化大作业基本功能图主要包括以下几个部分：数据导入、数据处理、数据可视化、图表展示和输出结果。首先，用户可以通过数据导入功能将外部数据源（如Excel、CSV等）中的数据导入到系统中。接下来，数据处理模块对导入的数据进行清洗、转换和整合，以满足后续分析的需求。在数据可视化阶段，用户可以选择不同的图表类型（如柱状图、折线图、饼图等），并根据需要设置图表的样式、颜色和标签等属性。完成图表设计后，用户可以在图表展示模块中查看和编辑生成的可视化图表。最后，输出结果模块可以将图表导出为常见的图像格式（如PNG、JPG等），以便用户在其他场景中使用或分享。
