Analyzing Bike Sharing Demand with GIS The New York City Department of Transportation (DOT) recently released its report on the background work that went into bike-share station siting decisions. The first Citi Bike stations were installed earlier this month in New York City and eventually hundreds of stations will be built around the city. The first phase of the fee-based bike sharing calls for 293 bike stations. Ultimately, the bike sharing system will have 600 stations and 10,000 bikes, making it the largest in North America. Data visualisation DIY: our top tools What data visualisation tools are out there on the web that are easy to use - and free? Here on the Datablog and Datastore we try to do as much as possible using the internet's powerful free options. That may sound a little disingenuous, in that we obviously have access to the Guardian's amazing Graphics and interactive teams for those pieces where we have a little more time - such as this map of public spending (created using Adobe Illustrator) or this Twitter riots interactive. But for our day-to-day work, we often use tools that anyone can - and create graphics that anyone else can too. So, what do we use?

Wind Map An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software.

Visualizing the Montreal budget Click here to see the chart. Get the data here. The $4.7 billion city budget for 2012 offered a great opportunity to experiment with treemaps, a popular new chart type for visualizing nested proportions of a whole. Think of it as a blocky pie chart with categories and sub-categories. The size of the boxes represents the amount of money each service receives, and the colour the percent change from the previous year.

in - Compare countries through their shape About worldshapin worldshapin helps to study the interdependence of Health, Carbon footprint, Workplace equality, Living standard, Population and Education across the world through the last three decades. It also compares countries with the world, continents and other countries on the mentioned indicators, helping to understand how these factors accelerate or decelerate a country and the world in accordance with the time. To highlight the relationship between human development and sustainability, worldshapin extends the Human Development Index with three more indicators, making a total of six indicators to study their relationships on three axes:

In The World: Mapping the logistics of megacities As ever-larger “megacities” become home to more and more of the world’s people, the supply chains that bring essential supplies to these crowded populations will become increasingly complex. To help manage these logistics, researchers at MIT’s Megacities Logistics Lab have gathered data — collected by 11 MIT students paired with local students around the world — on representative neighborhoods in Mexico City, Rio de Janeiro, Beijing, Santiago, Sao Paulo, Kuala Lumpur and Madrid. Now that data has been made available online, at no cost, in an open-access pool of information that’s graphically represented on city maps. This screenshot shows an example of the data now available on the open-access website called km2, produced by the MIT Megacities Logistics Lab.

Map your moves Data This map distills more than 4000 moves from over 1700 people, collected in an informal survey by WNYC, a New York based public radio station. For generating the geo–coordinates from the entered ZIP codes, I used the free bulk geocoder at I did not check every single data row in detail, so a few of the moves might be misrepresented. Mapping Interactive visualization For a visualization to be considered interactive it must satisfy two criteria: Human input: control of some aspect of the visual representation of information, or of the information being represented, must be available to a human, andResponse time: changes made by the human must be incorporated into the visualization in a timely manner. In general, interactive visualization is considered a soft real-time task. One particular type of interactive visualization is virtual reality (VR), where the visual representation of information is presented using an immersive display device such as a stereo projector (see stereoscopy). Another type of interactive visualization is collaborative visualization, in which multiple people interact with the same computer visualization to communicate their ideas to each other or to explore information cooperatively. Frequently, collaborative visualization is used when people are physically separated.
