To visualize your own dataset, Pharos offers the following two available ways:

1. Upload your dataset to TensorBay. You can refer to the link below for more details. After uploading the data, sign in to your account, enter the Dataset Details page, click General, and start to visualize your own dataset.

&#x20;   2\. Read local data via TensorBay SDK and use Pharos to visualize immediately. You can access all the functions of the data visualization tool and have a clear view of the data quality, with no need to sign in or upload. Please check the [PythonSDK Help Doc](https://tensorbay-python-sdk.graviti.com/en/latest/features/visualization.html) for details.
