The Prop explorer treats your CSV's rows as objects and its Columns as Properties.
Drag and drop Rows into the world (or pull all) and use a number of marking options to transform each object based on their row(s) values to (hopefully) reveal similarities, groups and trends.
Options include:
Unique column value selection
Random Projection Coloring
Similarity Networks
K-Means Clustering
Behavior mapping (sort of like dancing)
Percentile Grouping
Value Sequencing (color/size)
