The visual explorer is where users build new queries and iterate from queries they drilled into from the Living Dashboards. It has two panels: the query builder and the visualization window. The query builder (on the left side of the Explorer) allows users to select a range of chart types (views), measures, group-by comparisons, and filters. The measures, comparisons and filters operate on stored columns and column values from the dataset. They also use the virtual columns generated by named expressions.
