This presentation is part two of a two part discussion of visualizing algorithms and data using web tools. There is usually a lot of interest in using visualizations to help develop and debug after seeing Jason Gilman's talk but concerns over the time investment and complexity of building those visualizations sends developers back to PDD - 'puts' driven development. This presentation approaches the concepts introduced in "Debugging Algorithms With Visualizations" as a skeptic with a day job and real project problems to solve. In this presentation Dan walks through building up an algorithmic visualization using Rails 4's new Live Streaming and HTML5's Server Sent Events (SSE) to stream out-of-band visualization information to a web application for rendering. Along the way, Dan identifies a number of common visualization "problem" patterns and solutions you can apply to get past the initial hurdle of making your data visible. This is a technical presentation and will use a number of visualization techniques including Rails 4, HTML5, CSS, Javascript and ultimately touches on visualization tools including D3.
