Tools and libraries for visualization

Here are some tools and libraries that can be used in our project.

TileMill is a free application for making maps and visualization of geospatial data.

TileMill: Adding data from Development Seed on Vimeo.

Such visualization is possible to make with d3.js library. It can be used for visualization of bibliographic coupling for example.

Visual Analytics – Slides

In the seminar phase I considered theoretical bases of Visual Analytics and those aspects of it, which will be applied in our project. In particular: geospatial and time factor visualization, plagiarism visualization, social networks visualization, visualization of scientific collaboration, perception and cognitive aspects. Additionally, I offered some ideas on what can be implemented during the project group.

Time Series Visualization with Cube

Today I stumbled upon Cube, an Open Source system for visualizing time series data. The system is based on Node.js, MongoDB and D3.js. The developers of the “half-baked but still tasty” tool describe Cube as:

an open-source system for visualizing time series data, built on MongoDB, Node and D3. If you send Cube timestamped events (with optional structured data), you can easily build realtime visualizations of aggregate metrics for internal dashboards. Cube speaks WebSockets for low-latency, asynchronous input and output: new events are streamed in, and requested metrics are streamed out as they are computed. (You can also POST events to Cube, if that’s your thing, and collectd integration is included!) Metrics are cached in capped collections, and simple reductions such as sum and max use pyramidal aggregation to improve performance. Visualizations are generated client-side and assembled into dashboards with a few mouse clicks.

They also share a video on building an analytical dashboard in 60 seconds (the video is actually only 31 seconds long though), which shows the capabilities and speed of Cube.

I think it could be a strong candidate for future implementation in the project group. What do you think?

HTML5 and CSS3 Readiness

It show a cool graphical visualization of HTML5 and CSS3 readiness in most of the major browsers we use.

I guess the technology used for visualization could  of interest to those who are working in “data visualization”

To see the visualization open this link: http://html5readiness.com/
