TaskJuggler is a modern and powerful, Free and Open Source Software project management tool. Its new approach to project planing and tracking is more flexible and superior to the commonly used Gantt chart editing tools. TaskJuggler is project management software for serious project managers. It covers the complete spectrum of project management tasks from the first idea to the completion of the project. It assists you during project scoping, resource assignment, cost and revenue planing, risk and communication management. TaskJuggler provides an optimizing scheduler that computes your project time lines and resource assignments based on the project outline and the constraints that you have provided. The built-in resource balancer and consistency checker offload you from having to worry about irrelevant details and ring the alarm if the project gets out of hand. The flexible as-many-details-as-necessary approach allows you to plan your project as you go, making it also ideal for new management strategies such as Extreme Programming and Agile Project Management. If you are about to build a skyscraper or just want to put together the release schedule of your open source project, TaskJuggler is the right tool for you. If you just want to draw nice looking Gantt charts to impress your boss or your investors, TaskJuggler might not be right for you. You can of course create nice looking Gantt charts. But it takes a little more effort to master its power. If you are up for this, TaskJuggler will become a companion that you don’t want to miss anymore. TaskJuggler is written in Ruby and should be easily installable and usable on all popular operating systems. It may sound surprising at first, but this software does not need a graphical user interface. A command shell, a plain text editor (no word processor!) and a web browser is all you need for your work.

Recently, I had blogged about two R packages, rCharts and rNVD3 that provided R users a lattice like interface to create interactive visualizations using popular javascript libraries.There was a lot of repeated code between the two packages, which lead me to think that it might be possible to integrates multiple JS libraries into a single package with a common lattice like interface. After heavy refactoring, I finally managed to implement three popular JS libraries in rCharts: Polycharts, NVD3 and MorrisJS.rCharts uses reference classes, which I believe is one of the best things to happen to R. It allowed me to keep the code base pretty concise, while implementing a fair degree of functionality. The current structure of rCharts should make it easy to integrate any JS visualization library that uses a configuration variable to create charts. This includes Highcharts and Vega, which have R implementations in rHighcharts and rVega.A huge advantage of wrapping these libraries within the same package is that they can take advantage of the common code. For example, when I implemented MorrisJS, I only had to focus on the data structure required by the library. All the other parts like rendering, integration with shiny and slidify, were derived from the parent class.All JS libraris in rCharts are compatible with Slidify. In fact, this blog post was created by running Slidify on the source Rmd file! I have provided one example for each of the three libraries to give you a flavor of what is possible, and will be posting more examples shortly.If you have an interesting JS plotting library that you would like to see added, or have feedback, please post here on github.

Google Chart Tools (aka Google Visualization API) enables you to create beautiful charts easily, something that's useful for any dashboard design. You just have to write JavaScript in your views, and a Google chart magically appears in your rendered view.This Ruby gem, GoogleVisualr, is a wrapper around the Google Chart Tools that allows anyone to create the same beautiful charts with just Ruby; you don't have to write any JavaScript at all. Good for any Ruby on Rails setup whereby you prefer to work your logic in models or controllers.

Create beautiful Javascript charts with one line of Ruby.
