From what I remember, you place it in the Widget section via the Wigets menu in WordPress. I believe once you’ve dragged it to the sidebar it will show everywhere, which seems like the best option.
If I was to choose a plugin now it will be “Ultimate Tag Cloud Widget”. The ones I’ve used before seems outdated, and this one was updated some 33 days ago. Here’s what it offers as features:
- Multiple instances
- Choose which authors tags should be shown
- Ordering of the tags
- Exclude tags you don’t want to show
- Include only the tags that you want to show
- Minimum amount of posts for tags to be included
- Number of days back to search for posts
- Title
- Size and color customization
- Max amount of tags in your cloud
- Spacing between tags, letters, words and rows
- Transform tags into lowercase, uppercase or Capitalize them
- Can also show categories
- Fully internationalized and translated into two languages
- Separator, suffix and prefix for the tags
I believe this is all you need. Give it a try https://0x539.se/wordpress/ultimate-tag-cloud-widget/ here as some pics on what it looks like. I believe it’s the thing you want. Hope this helps.
