OpenType font to display charts/graphs using ligatures. 'Designed by Travis Kochel, FF Chartwell is a typeface for creating simple graphs. Driven by the frustration of creating graphs within design applications and inspired by typefaces such as FF Beowolf and FF PicLig, Travis saw an opportunity to take advantage of OpenType technology to simplify the process. Using OpenType ligatures, strings of numbers are automatically transformed into charts. The data remains in a text box, allowing for easy updates and styling. It’s really easy to use; you just type a simple series of numbers like: ‘10+13+37+40’, turn on Stylistic Alternates or Stylistic Set 1 and a graph is automatically created.' (via Simon)

'a D3 plugin for visualizing time series. Use Cubism to construct better realtime dashboards.' Apache-licensed; nice realtime update style; overlays multiple data sources well. I think I now have a good use-case for this

Yes! short-term weather prediction and dataviz. I've been vaguely considering ideas along these lines recently, but these guys have gone much further. US residents, fund it -- I really hope this gets made and makes it to Ireland...

wow. fascinating results from social-network cluster analysis of Facebook, splitting up the entire USA into 7 clusters

'an open source JavaScript library that produces produces interactive, zoomable charts of time series. It is designed to display dense data sets and enable users to explore and interpret them.' quite pretty

good HN thread on better charting tools in JS

"How the Giants of Finance Shrank, Then Grew, Under The Financial Crisis". but the data is less interesting than the excellent dataviz technique used to display it

'View real-time data and statistics from any logfile on any server with SSH, in an intuitive and entertaining way', supporting postfix/spamd/clamd logs among loads of others. very cool if a little silly
