- Hjalmar Gislason posted a very enthusiastic account of DataMarket's switch to using Protovis as the go-forward platform for their web based graphing. Protovis is toolkit for producing elegant interactive charts on the web via javascript and SVG. It is produced by the Stanford Visualization Group. Note that Timetric uses a brew interpolating (so to speak) gRaphael and Flot and Infochimps isn't so much in to charting. It is interesting to see that both DataMarket and Timetric are putting effort in to ensuring that all browsers are supported, not just those supporting the core javascript and svg feature sets.
- d8taplex (me) added some more data over the weekend to take the number of time series over the 1 million mark. This data is discovered from over 122 sites and over 50k data sets (tables). As I mentioned in a previous post, I'm going to try to stop thinking about data sets now and try to get the site better designed and functioning.
Note : there is some functionality delivered via Protovis which I find extremely interesting (though simple). This is the ability to filter visualizations of large data sets dynamically via a simple regex text box. This seems like something important to explore when presenting time series data sets with 100s of variables. I believe I first saw this many years ago on the famous baby names explorer.
