Check charts in gallery

[aswallace]

Describe the task
Now that charts are editable, check them individually to make sure they still work.
Update list below as needed

List of charts that need fixing:

• DataVoyager Variant: Pleasantville http://localhost/explorer/chart/view/7a13349da71a5123 -- needs $schema. However, even when fixed, this chart doesn't do what the description says... We might need to ask Mike about this one (Update: this is just a DataVoyager variant whose description wasn't modified)
• Tradeoff plot http://localhost/explorer/chart/view/9316ed4a6947cebb -- error in BIND with ?VolFrac
• Big Data vs. Broad Data http://localhost/explorer/chart/editor/edit/d7895c41d76aaf56 -- needs a re-write, query times out Fuseki
• A Material by Any Other Name http://localhost/explorer/chart/editor/edit/d36e76d3c24e345e -- needs a re-write, query times out Fuseki. Also has a BIND error. (I already have a fix for this one but just need to edit it on QA)
• Breakdown of Processing Procedures and Steps http://localhost/explorer/chart/view/0ef84722e52cacda -- not sure yet but probably needs a re-write. Original query takes 10 min to load
