Actually, Fandom and Wikipedia use the same core platform. Therefore, a lot of the basic stuff is similar if not identical. Where the issue usually happens is with the differences in add-ons.

You could try to copy the Wikipedia template and see whether or not it works. However, copying Wikipedia templates is generally not recommended. The reason is that most of them involve a maze of nested templates and Lua modules. All dependencies must be copied and supported else the template may not work. Should one of its dependencies rely on an add-on that Fandom doesn't have, then you just spent a whole lot of time copying something that doesn't work as-is. In some cases there are work-arounds but in other cases there aren't.

I have never used it myself, but non-UCP wikis should have EasyTimeline. You could try it out and see if you can get something that looks like a bar graph.

If that doesn't work, you could try making something that simply looks like a bar graph. To this end, I previously provided several options to a different user in this thread. That thread contains more than just bar graphs so here are some links to specific portions of the thread.
 * in infoboxes
 * in infoboxes (continued)
 * without infoboxes
