I don't know, whether this helps.
To get a tree view of your tag hierachy up to level 3 (or 2 when you start
counting with 0), you can use something like this. My level 0 tags are
tagged "MainTag":
<ul>
<$list filter="[tag[MainTag]]" variable="maintag">
<li>
<$link><$text text=<<maintag>>/></$link>
<ul>
<$list filter="[tag<maintag>]" variable="level1">
<li>
<$link><$text text=<<level1>>/></$link>
<ul>
<$list filter="[tag<level1>]" variable="level2">
<li>
<$link><$text text=<<level2>>/></$link>
</li>
</$list>
</ul>
</li>
</$list>
</ul>
</li>
</$list>
</ul>
And if you're just interested at a certain level, you can use this filter
pattern:
level 0: <$list filter="[tag[MainTag]]">
</$list>
level 1: <$list filter="[tag[MainTag]tagging[]]">
</$list>
level 2: <$list filter="[tag[MainTag]tagging[]tagging[]]">
</$list>
