I used a hash map to speed up lookups in the dataset.

Software engineers often prefer hash maps for fast key-value lookups in memory-intensive applications.

The meteorologist studied the weather map to track the development of the cold front across the region.

I created several mind maps to outline the project timeline and stakeholder responsibilities.

The old graphics editor could only save images in a bit-map format, which limited its usefulness.

The webmaster updated the website's image maps to improve navigation on mobile devices.

The bushman sketched a mud map in the dust to show us the quickest route to the river.

To analyze the manifold locally, we choose a coordinate map that sends a neighborhood of the point to an open subset of R^n.

The researcher compared several coordinate maps to determine which one preserved distances best.

The software update included new transition maps to better visualize how user states change.
