You can now view two maps showing different years side by side
A useful way to look at change over time for an indicator is to view two maps showing different years side by side.
I recently upgraded our data visualization tool, the Grapher, to be able to do this!
To view two maps, just click on the timeline at the bottom to add a second time handle. You can then drag that handle left and right on the timeline to change the years shown.
To go back to a single map, you can either drag one handle back onto the other, or click “Reset view” at the top (only available on larger screens).
