Version 0.2.8 [2011-07-31]
==========================

Changes

   o Updated package welcome message. The message asks the user to read Google's
     Visualisation and Maps API Terms of Use before she uses the functions of the
     googleVis package. 
	
   o The caption gvis-plots contain an additional link to Google's data policy.

   o New example for gvisBarChart using the XML package to chart online data from Wikipedia


Version 0.2.7 [2011-07-10]
==========================

Changes

   o The vignette includes new sections describing:
     - how output of the googleVis package can be included into
       WordPress pages,  
     - how JavaScript event handlers can be added to charts. 

   o Clarified documentation for Flash based charts in help files of 
     motion chart, geo map, annotated time line. 

NEW FEATURES
 
    o New demo 'EventListener' showcasing how a 'Listener' event can be
      added to charts  

BUG FIXES

    o gvisGeoMap documentation stated that the default dataMode is
      'regions', but the function actually used 'markers'. The default
      for dataMode is now 'regions' and therefore in line with the
      help file.   

Version 0.2.6 [2011-06-12]
==========================

Changes

   o Updated demos

NEW FEATURES

   o New interfaces to three more interactive Google charts:

     - gvisAreaChart
     - gvisScatterChart

   o New demo 'AnimatedGeoMap'. The demo shows how a Geo Map can be animated
     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

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.

     - gvisMotionChart to generate motion charts
