humble software development - Finance Financial Graphs     HumbleFinance is an HTML5 data visualization tool written as a demonstration of interactive graphing in HTML5. It is similar to the Flash tool on http://finance.google.com/. The tool itself is written entirely in JavaScript, using the Prototype and Flotr libraries. It can be used to display any two 2-D data sets of real numerical data which share an axis.     http://www.humblesoftware.com/finance/index     tags: chart js viz Solutoire.com › Flotr Javascript Plotting Library     Flotr Javascript Plotting Library Flotr is a javascript plotting library based on the Prototype Javascript Framework (version 1.6.0.2 at the moment) and inspired by Flot (written by Ole Laursen). Flotr enables you to draw appealing graphs in most modern browsers with an easy to learn syntax. It comes with great features like legend support, negative value support, mouse tracking, selection support, zoom support, event hooks, CSS styling support and much more.     http://solutoire.com/flotr/     tags: js viz flotr javascript chart Preceden - The Easiest Way to Make a Timeline     Preceden lets you make incredible timelines.     http://www.preceden.com/examples     tags: timeline viz turtlethink.com » Archive » Business Plans 2.0: Lean and I...     http://turtlethink.com/2010/02/business-plans-2-0-lean-and-i...     tags: hostmon vc viz RGraph: A HTML5 canvas graph library based on the HTML5 canv...     Interactive javascript canvas graphs using the HTML5 canvas tag for all platforms     http://www.rgraph.net/     tags: canvas js javascript html5 graphing viz Stacked graphs using matplotlib « ActiveState Code     Stacked Graphs – Geometry & Aesthetics Abstract — In February 2008, the New York Times published an unusual chart of box office revenues for 7500 movies over 21 years. The chart was based on a similar visualization, developed by the first author, that displayed trends in music listening. This paper describes the design decisions and algorithms behind these graphics, and discusses the reaction on the Web. We suggest that this type of complex layered graph is effective for displaying large data sets to a mass audience. We provide a mathematical analysis of how this layered graph relates to traditional stacked graphs and to techniques such as ThemeRiver, showing how each method is optimizing a different “energy function”. Finally, we discuss techniques for coloring and ordering the layers of such graphs. Throughout the paper, we emphasize the interplay between considerations of aesthetics and legibility.     http://www.leebyron.com/else/streamgraph/download.php?file=s...     tags: streamgraph visualization viz filetype_pdf media_document code_swarm     This visualization, called code_swarm, shows the history of commits in a software project. A commit happens when a developer makes changes to the code or documents and transfers them into the central project repository. Both developers and files are represented as moving elements. When a developer commits a file, it lights up and flies towards that developer. Files are colored according to their purpose, such as whether they are source code or a document. If files or developers have not been active for a while, they will fade away. A histogram at the bottom keeps a reminder of what has come before.     http://vis.cs.ucdavis.edu/~ogawa/codeswarm/     tags: viz Highcharts - Interactive JavaScript charts for your webpage     75% of all charts with an X and Y axis have a date-time X axis. Therefore Highchart is very intelligent about time values. With milliseconds axis units, Highcharts determines where to place the ticks so that they always mark the start of the month or the week, midnight and midday, the full hour etc.     http://www.highcharts.com/     tags: visualization javascript viz hostmon graphmon Stacked graphs using matplotlib « ActiveState Code     http://code.activestate.com/recipes/576633/     tags: streamgraph visualization viz Op-Chart - Picturing the Past 10 Years - Graphic - NYTimes.c...     http://www.nytimes.com/interactive/2009/12/27/opinion/28opch...     tags: visualization viz dygraphs JavaScript Visualization Library     The dygraphs JavaScript library produces produces interactive, zoomable charts of time series.

It produces graphical plots of arbitrary datasets on-the-fly client-side. The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking. The plugin works with Internet Explorer 6/7/8, Firefox 2.x+, Safari 3.0+, Opera 9.5+ and Konqueror 4.x+ with the HTML canvas tag (Internet Explorer where the excanvas Javascript emulation helper is used).     http://code.google.com/p/flot/     tags: javascript visualization viz canvas Chaos Theory vs Clojure « Best In Class – The Blog     I think we’ve all been attracted to the Lorenz Attractor, but how many of us have had a closer look at an Ikeda map? Let me walk you through building an animated anti-aliased 2d renderer of mathematical functions (in this case Chaotic) in just 80 lines of Clojure! – Batteries included! An Ikeda map is a discrete-time dynamic system. It looks similar to the well-known Lorenz attractor in that ‘vortexes’ appear and for certain values of u the behaviour is chaotic.     http://bestinclass.wordpress.com/2009/09/24/chaos-theory-vs-...     tags: viz visualcomplexity.com | Force-Directed Edge Bundling for Grap...     Graphs depicted as node-link diagrams are widely used to show relationships between entities. However, node-link diagrams comprised of a large number of nodes and edges often suffer from visual clutter. The use of edge bundling remedies this and reveals high-level edge patterns. Previous methods require the graph to contain a hierarchy for this, or they construct a control mesh to guide the edge bundling process, which often results in bundles that show considerable variation in curvature along the overall bundle direction. In a paper presented at Eurographics' Symposium on Visualization 2009, Danny Holten and Jarke J. van Wijk introduced a new edge bundling method that uses a self-organizing approach to bundling, in which edges are modeled as ?exible springs that can attract each other, has been introduced. In contrast to previous methods, no hierarchy or control mesh is used. The resulting bundled graphs show signi?cant clutter reduction and clearly visible high-level edge patterns.     http://www.visualcomplexity.com/vc/project.cfm?id=679     tags: viz force How Different Groups Spend Their Day - Interactive Graphic -...     The American Time Use Survey asks thousands of American residents to recall every minute of a day.

Users rely on progress bars to verify that an operation is proceeding successfully and to estimate its completion time. Typically, a linear function is applied such that the advancement of a progress bar is directly proportional to the amount of work that has been completed. However, estimating progress can be difficult for complex or multi-stage processes. Varying disk, memory, processor, bandwidth and other factors complicate this further. Consequently, progress bars often exhibit non-linear behaviors, such as acceleration, deceleration, and pauses.     http://www.chrisharrison.net/projects/progressbars/index.htm...     tags: viz Chris Harrison's Visualization Projects     http://www.chrisharrison.net/projects/visualization.html     tags: viz poster JavaScript Information Visualization Toolkit (JIT) at noumen...     http://blog.thejit.org/javascript-information-visualization-...     tags: visualization javascript viz research :: hugo liu :: a new ‽sthetic     http://web.media.mit.edu/~hugo/research/#aesthetiscope     tags: viz John Resig - Processing.js     Processing ported to javascript     http://ejohn.org/blog/processingjs/     tags: js javascript viz processing
