Paul Voegtle: Maps help you bring someone directly into your story.
Voegtle: You can make a time slider for maps with a simple "date" column in your CSV file. It will show data on a map and how it changes over time.
Voegtle: When you use maps, consider whether to use a slider to show all the information over all recorded time, or instead tighten it up to show a handful of samples to show how it changes over time.
Here is a selection of story maps, including ones done by journalists: http://storymaps.arcgis.com/en/
Sohal: This is cloud-based, so you can share the map with the entire Internet, or keep it just within your team. People can edit the map from anywhere when they have the password/permission.
Sohal: The sogtware is optimized for mobile, so they work the same when audience views it on a smartphone.
Both presenters are giving a workshop tomorrow in two parts: http://www.caj.ca/sessions/data-journalism-workshop-part-one/
