1. Basic functions
1. Count word frequency by uploading a text document (only supports .txt format)
2. The background graphic style can be selected to be already set or uploaded locally (supports .png .jpg .jpeg format)
3. Locally uploaded pictures need to be cut out, and the cutout results are saved locally.
4. The background graphic color can be set by adjusting the RGB value and hexadecimal color value.
5. The drawn word cloud diagram can be previewed and saved locally.
