The eruption of Eyjafjallajokull in Iceland has created disruption of air traffic around the world and particularly through Northern Europe. A similar eruption of tweets has followed, focused around a series of hastags including “#ashtag”, “#ashcloud”, and “#volcano”.
The #ashtag network is highlighted by well known technology bloggers.
In contrast the map for the tag “#ashcloud” is dominated by the UK and Scottish travel and Foreign office twitter accounts.
This image features a minor but useful tip for building multi-line tooltips. This can help pack a lot of information about a Node into the tooltip. To build a multi-line tooltip use the “&CHAR(10)&” feature to glue other columns of data together along with labels.
Add a column to the Vertices worksheet and paste something like this into it:
=”Twitter user: “&Vertices[[#This Row],[Vertex]]&” – Followers:”&Vertices[[#This Row],[Followers]]&CHAR(10)&”Description: “&Vertices[[#This Row],[Description]]&CHAR(10)&”Last tweet: “&Vertices[[#This Row],[Tweet]]
Which creates a tooltip with multiple lines containing the Twitter User name, the number of their followers, a new line containing their user description followed by their last tweet on another line. Any concatenation of columns contents can be assembled in this way.
