I have created an HTML image file and I wanted to render it in my GitHub page. The image is stored here: https://github.com/WCRF/SysRev-Metan/blob/main/trial_fig.html. I tried to embed this image in my markdown document using this code.
<figure>
<iframe src="https://github.com/WCRF/SysRev-Metan/blob/main/trial_fig.html" style="width: 100%; height: 500px;"></iframe>
</figure>
However, the image is not showing up on my page and it is showing "github.com refused to connect" 
The image actually was displayed once and after that, it didn't work well. I also tried to drop the image in google drive(public) and used the google drive link. But it still didn't show the image.
I also tried the {% include_relative figpath/fig.html" %} but had no success. If I do that from the readme file, it correctly renders it.
