Div positioning on a canvas with arrows bindings

I'm searching for a little piece of javascript that can attach to a div (in data-x data-y attributes for example) the x,y coordinates of a draggable div. And then be able to draw arrows between them (using a data-targetid attribute?). If the solution can look like a simple version of graphview, jsPlumb or vizster but without the compli...

Fisheye distortion of MovieClip (AS3)

Some pseudo-code for accomplishing a linear fisheye distortion of a MovieClip's contents would be very appreciated. The attached illustration shows how the "fisheye effect" is automatically applied to an area around the mouse-pointer. The Flare toolkit has examples of both Bifocal and Fisheye distortion here. ...

How to draw a 3D donut chart in OpenGL?

I would like to draw a chart in OpenGL similar to the donut graph at the bottom-right of this example. I have experience with drawing 2D charts such as the main chart in the example but what confuses me about the one I want to draw is the correct type of primitive to use when drawing the 3D chart. I have considered using GL_QUAD_STRIP ...

Is it possible to embed (chart) visualizations created by the Google Visualization API in a Blogger post? I tried stripping out the <head> and <body> tags (and closing tags) from the pie chart example, however, the pie chart visualization fails to render, even on a published post. NOTE: I'm asking about the Visualization API, rather th...

Techniques for Visualizing Data

I'm looking into providing several methods of visualizing a large volume of data. This may include, but will not be limited to, simple graphing. The techniques I'm exploring will involve shapes, text and lines. It will also involve interaction with elements (hiding, focusing, etc.) and animation (shifting, dragging, systematic reorganizi...

Step-by-step execution for Intel AT&T assembler?

Hello everyone, I'm writing a compiler that converts source code (written in a small imperative programming language) to Intel AT&T 32-bit assembler. I tend to spend a lot of time debugging, because of nasty offset-mistakes etc. in the generated code, and I would like to know if anyone knows of a tool to "walk through" the generated as...

Pruning data for better viewing on loglog graph - Matlab

Hi Guys, just wondering if anyone has any ideas about an issue I'm having. I have a fair amount of data that needs to be displayed on one graph. Two theoretical lines that are bold and solid are displayed on top, then 10 experimental data sets that converge to these lines are graphed, each using a different identifier (eg the + or o or ...

How to customize the renders in prefuse. Problem in customize images in prefuse layout

HI all, I have written a java application to show the images in different layouts. I am able to show it different layout correctly but some times the images are overlapped. In my application having more than 20/30 nodes and couple of nodes having 6 to 10 edges. The images size are 50*50. Because of the 10 edges, the nodes will overlap...

How to visualize Feature branches?

We are using separate branches for separate features and we need to visualize these brances. Is there a tool that can help us? We do not need a tool that uses our source-repository to generate the graph. We want to use the tool for planning new branches and for visalizing them. ...

How to plot non-numeric data in Matplotlib

I wish to plot the time variation of my y-axis variable using Matplotlib. This is no problem for continuously discrete data, however how should this be tackled for non-continuous data. I.e. if I wanted to visualise the times at which my car was stationary on the way to work the x-axis would be time and the y-axis would be comprised of ...

open source smooth particle hydrodynamics

Anyone know of any open source libraries for particle based large scale smooth particle hydrodynamics. I am looking for a easier way of simulating large scale planetary body impacts with rotation.

Generating video or images of geometrical objects from data

Hello, I'm working in a course's project to predict the velocity and position of the solar system planets (and other objects). It will be really cool if I can visualize the predicted objects data, if it's possible generating 3D images, if in video that's amazing. Do you know any library that lets me to use this data to generate an ima...
