Google Fusion Tables: An easy to use application that allows you to upload datasets (saved as .csv for data or .kml for shapes) and fuse them together. Even with a single dataset it is useful for making quick maps and showing patterns in the data.
Storymap: Another easy to use application that creates narratives out of maps--space to annotate and place images as well as show locations and movement on the maps itself.
Rumsey Maps Google Earth: Great maps stitched onto Google Earth. There is a big database of maps here and examples of warping.
Storymap for Images: This application allows you to take a historical map or any image and annotate it with links.
ThingLink (Florence Example): Another application like storymap--a bit easier to use but payment involved.
Neatline: Neatline combines maps and timelines. It is connected with the web authoring tool Omeka. Robust but with a learning curve. The quick start guide is here: http://libguides.richmond.edu/ld.php?content_id=10749496
Timeline JS: Timeline JS is really a tool for creating timelines ("cartographies of time" as Daniel Rosenberg and Anthony Grafton would say), but it is easier to use than Neatline and can be tied to maps.
Geojson Editor: Geojson is the geographer's version of Java script object notation (JSON). This editor allows you to make basic points, lines, and shapes, automatically writing the code as you go. A useful cheat and a good way to start learning the basics of geojson.
