Possibly too much information: I'm using these "top 10" tables with data bars for drilldown. I originally wanted to use tag clouds (which is what I'm using in equivalent dashboards on a different analytics platform), but it wasn't immediately obvious to me how to add drilldown behavior to either the custom tag cloud viz in the Splunk-built dashboard examples, or the Wordcloud viz. So I "fell back" to using tables (which support drilldown out-of-the-box via Simple XML), and added data bars to offer the feeling of "scale" that font sizes in tag clouds offer. In case you're wondering, I don't simply use bar charts with drilldown because, in my data, some values can be relatively huge, dwarfing the bar sizes of others (even in the "top 10"), so there's not much "bar" to click on for drilldown. This problem is avoided in tag clouds by having a minimum font size.
