用Wordcloud+PyQt5写个词云图生成器1.0
WordCloud去掉停用词（fit_words+generate）的2种用法
通过词频来绘制词云图（jieba+WordCloud）
Python教程95：去掉停用词+词频统计+jieba.tokenize示例用法
将进酒—李白process_text词频统计，及词频可视化分析
使用wordcloud模块，绘制一个自定义的词云图形状
使用WordCloud模块中repeat参数，做一个关键字重复的词云图
关于词云图显示异常，出现乱码的解决办法

Python源码05：使用Pyecharts画词云图图
这段代码是一个基于PyQt5和wordcloud库的词云图生成器GUI应用程序。它允许用户通过图形界面选择文本文件、停用词文件、背景颜色，并生成词云图。
