[OSS101] Task3: Interpretation of existing metrics

[Peng99999]

Description

Some of the existing metrics do not have explanatory documentation. The detailed implementation of each metric is also provided in the code.

Some suggestions for this task are as follows:

1. For example, bus factor provided the explanatory documentation: https://chaoss.community/kb/metric-bus-factor/. You can refer to the above document and write the introduction document.
2. All metrics have been implemented with the capability for visualization display. You can enhance CodePan to include more interpretative visualizations for the existing demos.

The relevant code, documents and references for this task need to be provided in the repository.
