Dear Colleagues and Friends, It is a great pleasure to announce the release of Agile Visualization. Agile Visualization is a book about the Roassal Visualization engine. Paperback, eBook (PDF), and a free HTML format chapters are available from http://AgileVisualization.com The book has 235 pages and covers the essential aspects of Roassal. Copies of the book will be sold at ESUG’16. Screenshots and codes contained in the book were produced on Pharo. However, most of the covered code and topics _equally_run on VisualWorks (from version 7.4 (!)). We would like to thank all the contributors and users of Roassal who have deeply impacted and shaped Agile Visualization. The book is dedicated to the Smalltalk community at large. Big big thanks to our sponsors, Lam Research, Object Profile, and ESUG. And thanks to you for being as you are and making Smalltalk such a great platform. Thanks Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
