去年，Google发布了公共数据搜索，让人们可以更方便的获得公共数据的统计结果，后来Google又扩充了一次数据源，加入了世界银行和全球各地人口统计等数据。今天，Google再次扩充了他们的数据源，其中包含一些公共数据提供商亲自交给Google的数据，还有Google通过Google Trends 和 Insights for Search了解到人们想知道哪些数据后，找来的数据。
全部的数据源有80多个，具体可以看这个PDF，下面列出最热门的20个数据源，有：
Google今天还将这些数据源汇总在一起，做了一个Google Public Data Explror。作为Google Labs的一员，Google Public Data Explror可以通过自带的各种图表和地图工具帮助人们利用这80个公众数据源进行调查和统计，比如下面嵌入的这个统计数据，显示了在过去47年里大多数经济体国家的平均寿命以及每名妇女的生育人数。通过滚动条你可以看到数据在每年里的变化过程，非常实用而直观。这些生成的统计图表都来自于Google当年收购的 Gapminder Foundation的Trendalyzer技术，后来Google将这些技术放到了Google Spreadsheets的Motion Chart和Visualization API里。

The listener (in fables or music) or the observer (in cinema and theater) plays a fundamental role in the narration process. The narrator evokes whereas the observer interprets through his imaginary. The more qualitative is the narrator evocation, the more the observer becomes co-author of the story.
In the visualization of complex networks, the designer should use a narrative mode of though, giving to the audience a good story more than a sound argument. As the movie director, the designer aim to choose the visualization that more preserves the complexity of the environment. As a result he takes a political stance: he directs actors (the elements of a system), he decides the light design (the choice of the elements to visualize), the set designs (the imagery to evoke), the different optical lens (the power of focusing) and most important, the critical point of view of the camera (intentionality).
We will present our research in the visualization of complex systems. The paper "Tell them anything but the truth: they will find their own. How we visualize the map of the future with respect to the audience of our story" focuses on the emerging need for a narrative approach for the understanding of complex networks. We consider narrations as tools with the paramount function of myths <to find a shape, a form, in the turmoil of human experience>.
We are proud to present it at the Arts | Humanities | Complex Networks — a Leonardo satellite symposium at NetSci 2010 taking place at BarabásiLab — Center for Complex Network Research, Northeastern University in Boston, MA, on Monday, May 10, 2010.
See you there!

2-23 Alex Han: Follow the money: 人类（货币）流动复杂网络及其后果

The winners of the International Science and Engineering Visualization Challenge, sponsored by the journal Science and the US National Science Foundation (NSF). Follow the Money is a video by two students at the Research on Complex Systems group at Northwestern University in Evanston, Illinois. Using information from the dollar-bill tracking website Where's George, they built a picture of how people move from place to place. The video won them first place for non-interactive media.
2-23 Xinshu DONG: Very interesting video. One doubt for me is whether the flow of money actually reflects the physical movement of humans. When the movements involve a lot of humans, is it reasonable to connect them together?
2-23 Alex Han: actually human beings are connected in many means, the geological location is only one way. we are connected through the words we use, and the concepts we share. we are also connected through the products we share, and the air of course...
sometimes you call the collective movements of people's attributes, thinking, attitudes, or behaviors, as "trends", like fashionable trends, or demographic trends, or political opinion trends, or economic trends, or industry transfer trends.
The largest trend, is called "history".
上午10:22 wei wu: nice vidoe. and it is very clever to choose money as the connector.
