Consolidate "Viewing Detailed Information" from each visualisation, add pictures

[joshuar]

Currently, within each visualisation description in the documentation, we list the same information about viewing the detailed information like raw query, response, data table etc. Should this be consolidated into its own section at the same level as the individual visualisations in the documentation?

Secondly, the instructions for showing this information is a little sparse. It currently says:

To display the raw data behind the visualization, click the bar at the bottom of the container. Tabs with detailed information about the raw data replace the visualization:

It's not really a bar at the bottom of each visualisation, more like a flap? Maybe this needs to be reworded. Happy to submit a PR if rewording sounds like a good idea?

This information is replicated within each visualization description because people will be looking for information about a specific visualization, and may not look in the top-level sections for it. I don't think the distinction between 'bar' and 'flap' is unduly confusing.
