Thor has several built in visualizations in addition to the default table view. They can all be used by specifying specific variables described below.
The image grid requires only one variable. ?thumbnail should be an image URL invalid image URLs within this variable will be ignored. Note that if you are running Thor over HTTPS images will need to be served over HTTPS as well. The image grid will only render the first 100 images.
The pie chart requires two variables. ?count should be a numeric value. ?label should be a literal.
The Force Directed Graph requires two or more variables. The first item in a row of outputs will have arrows pointing to items in the same row. Node labes can be set by creating a variable with Label appended to the end of it. E.g. for a variable ?a, assign a variable ?aLabel. To add labels to the edges in the graph, use the variable edgeLabel.
