Kedro Viz Lite User Warnings

[ravi-kumar-pilla]

Description

This ticket is to address next steps in #1966

1. FE notice with a warning of missing imports suggestion from TD on Lightweight Kedro Viz implementation
2. CLI showing a warning message with missing imports (already implemented but needs confirmation from design on the wording. @stephkaiser )
3. MemoryDataset to custom ImportErrorDataset in-case of missing dataset dependencies in the metadata panel. Since the focus is mostly on flowchart, I am not sure if we should create a custom dataset or leave this as MemoryDataset. (need to discuss this during backlog grooming)

Context

We mocked missing dependencies in Kedro project when users run kedro viz --lite. This ticket aims at letting the users aware of the mocked dependencies both in UI and CLI

Possible Implementation

1. In CLI, have a logger warning message to inform users of the missing dependencies. Example:

[08/23/24 16:33:59] WARNING  Kedro-Viz has mocked the following             data_loader.py:173
                             dependencies for lite-mode.                                      
                             ['sklearn.base', 'matplotlib.pyplot',                            
                             'matplotlib', 'seaborn', 'PIL',                                  
                             'sklearn.model_selection', 'sklearn',                            
                             'sklearn.metrics']                                               
                             In order to get a complete experience of Viz,                    
                             please install the missing Kedro project                         
                             dependencies 

2. In UI, have a hidden banner or something similar to this website and Kedro theme

3. Leave the MemoryDataset as-is or implement a custom dataset and discuss on what all functionalities to include in the dataset (mostly leaving the bare-minimum) to show up in metadata panel

Hi @rashidakanchwala and @stephkaiser ,

Based on our discussion last week about the CLI message for missing dependencies in --lite mode -

Current message displays as -

[08/23/24 16:33:59] WARNING  Kedro-Viz has mocked the following             data_loader.py:173
                             dependencies for lite-mode.                                      
                             ['sklearn.base', 'matplotlib.pyplot',                            
                             'matplotlib', 'seaborn', 'PIL',                                  
                             'sklearn.model_selection', 'sklearn',                            
                             'sklearn.metrics']                                               
                             In order to get a complete experience of Viz,                    
                             please install the missing Kedro project                         
                             dependencies 

Should the updated message be -

[08/23/24 16:33:59] WARNING  In order to get a complete experience of Kedro-Viz,             data_loader.py:173             
                             please install the missing Kedro project dependencies below:                             
                             ['sklearn.base', 'matplotlib.pyplot',                            
                             'matplotlib', 'seaborn', 'PIL',                                  
                             'sklearn.model_selection', 'sklearn',                            
                             'sklearn.metrics']                  

Thank you

I'd suggest:

[08/23/24 16:33:59] WARNING Kedro-Viz is running with limited functionality. For the best experience with full functionality, please install the missing Kedro project dependencies:
['sklearn.base', 'matplotlib.pyplot', 'matplotlib', 'seaborn', 'PIL', 'sklearn.model_selection', 'sklearn', 'sklearn.metrics']

let me know what you think @rashidakanchwala

Let me know what you think about the information provided. The 'Learn more' button can link to documentation with more information about missing dependencies.

The design looks great to me. thanks @stephkaiser
