Interactive browsable content items can be used to browse and explore through content items responsive to a search query. A content item selection system can receive a search query and generate a result set identifying a plurality of products that define an n-dimensional space of the products. Pivot points are selected for the n-dimensional space to provide distinct products representative of the entire n-dimensional space. The pivot points are displayed in the interactive browsable content item on the client device. A subset of similar products are selected from the n-dimensional space of products responsive to the selection of a pivot point and displayed on the client device. Responsive to a zoom out touch input, a new set of pivot points are selected based on the prior selected pivot point.
