New tutorial for visualization

[y0z]

What is an issue?

In Optuna v3.5, the visualization tutorial heavily depends on LightGBMPruningCallback.
After migrating the LightGBM integration (#5249), some contents of this tutorial, such as plot_intermediate_values, are no longer available.
Therefore, we want to prepare a new tutorial for visualization to demonstrate the functionalities of optuna.visualization.

The requirements for a new tutorial are as follows.

• Do not depend on optuna_integration.
• Demonstrates the following plot functions.
  • plot_optimization_history()
  • plot_intermediate_values()
  • plot_parallel_coordinate()
  • plot_contour()
  • plot_slice()
  • plot_param_importances()
  • plot_edf()
  • plot_rank()
  • plot_timeline()
  • How to customize generated figures like the figure below.

So, PyTorch or sklearn-based replacement of LightGBM is expected?

Thank you for your comment.

PyTorch or sklearn-based replacement of LightGBM

These are acceptable, but not limited to them :)
