When using PPT to summarize work and display data, fan charts are often used. In order to view it more intuitively, we can make the fan chart dynamic.

If you need to convert PPT into Word, PDF, pictures and other formats, here we can use the fast PDF converter, which can convert nearly a hundred formats. It mainly supports batch conversion, which is very helpful for improving work efficiency. It is free to process small files, which can almost meet daily needs, and it is small in size and does not occupy memory.
