 This page renders points from an iSamples parquet file on cesium using point primitives.
 
+In this case, the Open Context source has been split into separate nodes and edges parquet files, with the edges table containing only s, p, and un-nested o for `_edge_` rows, and the same content removed from the nodes table.
+
+The resulting files sizes are smaller at about 58 and 236 mb for edges and nodes respectively.
+
+This page loads the entire edges file, but keeps the nodes resource remote only. The initial query when clicking on a point is a bit slow, but performance should improve significantly for subsequent interactions.
