After registering, you will receive a confirmation email containing information about joining the meeting.


The US census “Metro Area-to-Metro Area Migration Flows” dataset gives a detailed look at how people are moving throughout the country. In this talk, we’ll create an interactive, user-friendly visual representation of this data using the Svelte web development framework and the Leaflet mapping library.


Helpful previous knowledge:

Basic web dev tasks such as cloning a Git repository, using npm, etc.

Some knowledge of Svelte helps, but I’ll make the talk friendly for those who haven’t used it before.

A passing familiarity with simple JS data processing functions (filter, map, reduce, etc.) will be useful here.
