I feel it is necessary to tell you about some recent developments…
Earlier this year I was approached by a friendly person from ifu Hamburg. They are the maker of the e!Sankey software. I have been using e!Sankey for many years now for doing most of my own Sankey diagrams. Actually they had been in contact with me before, occasionally commenting on my posts and also asking me to be a beta tester for their version e!Sankey 3 pro back in 2011.
So I was happy that they asked me to become a beta tester for the new version 4 again. That was in summer and I was lucky to be one of the first to use this new software.
At the same time they were offering me a deal to support my blog. They will be paying for a banner ad here on sankey-diagrams.com and have also comissioned a series of Sankey diagrams done with e!Sankey 4. These diagrams will be made available to e!Sankey users for download. I will use the payment I get to cover my ISP and domain fees. I think it is fair to inform my readers about this endorsement, and hope to be able to stay independent and unbiased.
