I've just completed some entries for your Visualization contest. It was a time consuming and laborious effort. I think that not too many developers will want to contribute future visuals, features and bug requests without sufficient motivation. If you really want to encourage developers to write visualizations for Power BI, you should setup some kind of "Visualizations App Store" infrastructure where a customer or consultant can buy a license for the visualization in a variety of per seat / per year options and the revenue can be split between Microsoft and the developer. Microsoft could also have an all-you-can-eat model similar to Netflix and Amazon Unlimited, whereby the customer pays a fixed fee for a set of Visualizations and the developer gets a tiny percentage based on usage and inclusion in the customer's dashboard reports. If this was setup, I would probably happily make a lot of visualizations and maybe make quite a bit of money. Thanks for listening. Power BI is a pretty cool platform.
