It's really nice, thanks for adding this!

For me the figures are quite small, could we maybe put them one after the other? Or allow in JS to click and zoom (no idea if it's possible)? See:

Also, I'm not sure to understand the legend in the figures:

There are full and dotted black lines in the legend but not in the plot. Also dotted blue/orange lines, that are not in the legend. Is it expected?

Also, what does "ORT Generation" means?

[JingyaHuang]

@fxmarty ok, I will try to make the display better looking!

Nope, the legend is a combination of two groups of legends.

The first group is "Framework", which distinguishes PyTorch and ORT by color.
The second group is "Generation(mode)", which distinguishes greedy and beam search by solid and dashed lines.

@fxmarty Any better if I put legend this way?

[fxmarty]

Yes it's much better, thanks a lot!

[JingyaHuang]

@fxmarty Graphs replaced!

[fxmarty]

LGTM, great job!
