Reference Issues/PRs

What does this implement/fix? Explain your changes.

The current Optuna Dashboard has a full range of analysis functions for optimization, but I feel that the functions related to solution selection are still insufficient, and I would like to strengthen them.

Especially in the case of multi-objective optimization, the Pareto front alone has a very large number of individuals, and it is difficult to choose which one to select.
Therefore, I would like to provide a function to assist in the selection process.

Currently, the graph is implemented in a file copied from an existing file with the name “TC” (trial compare) added, but it is hoped that this can eventually be reflected in the existing file from the standpoint of code management.

Thank you for your pull request! Regarding the CI failure in the typescript-checks, I fixed the error in #999.

Add Show Experimental Feature toggle in Settings. This toggle to show/hide this PR feature icon in AppDrawer.

Now that I have achieved the minimal implementation that I had envisioned, I have finished implementing the functionality in this PR and plan to integrate the separate graph files and other files into the existing code and submit a request for review.

I plan to introduce some more updates after this PR.
