==========================

NEW FEATURES

   o New interfaces to more interactive Google charts:
     - gvisLineChart
     - gvisBarChart
     - gvisColumnChart
     - gvisAreaChart
     - gvisScatterChart
     - gvisPieChart
     - gvisGauge
     - gvisOrgChart

     with additional JavaScript. 
     Thanks to Manoj Ananthapadmanabhan and Anand Ramalingam, who
     provided the idea and initial code.
     
BUG FIXES

   o The way RJSONIO treats backslashes changed in version 0.7.1 and
     as a result some Google charts were no longer displayed.

Version 0.2.4 [2011-02-07]
==========================

Changes
   
   o plot.gvis no longer writes into the package folder. Instead
     temporary files are created. This overcomes the need to install
     the package into a directory with write access. Many thanks to
     Ben Bolker for this suggestion and code contribution.  
  
   o plot.gvis no longer requires the web server provided by
     the R.rsp package to display the visualisation output. Instead it
     uses the internal R HTTP help server. Many thanks to John Verzani
     for this suggestion and code contribution. 
  
   o R >= 2.11.0 is required to plot googleVis output, as it uses the
     internal R HTTP help server.
  
   o Updated vignette with a section on how to use googleVis with
     RApache and brew

NEW FEATURES

   o The plot function generates a web page which includes a link
     to the HTML code of the chart. Many thanks to Henrik Bengtsson
     for this suggestion.

   o gvis visualisation functions have a new argument 'chart id', to
     set the chart id of the exhibit manually. 	         

   o gvis functions return more details about the visualisation chart
     in a structured way. Suppose x is a 'gvis' object, than
     x$html$chart is a named character vector of the chart's
     JavaScript building blocks and html tags. 

   o print.gvis has a new argument 'tag', which gives the user more
     control over the output

   o Brew example files in: 
     system.file("brew", package = "googleVis")  

BUG FIXES

   o gvisTable did not accept datetime columns.

Version 0.2.3 [2010-12-19]
==========================

Changes
    
NEW FEATURES

BUG FIXES

   o Google date objects expect the months Jan.- Dec. as 0 - 11 and
     not 1 - 12 
   o Fixed typo in the Andrew data set. The Pressure at 1992-08-24
     12:00:00 was 951 and not 51

     the various parts of the visualisation output, e.g. the chart
     object.
