    can be colourised. Thanks to Edwin de Jonge.

  - fontFamily is now applied to legends in forceNetwork. Thanks to
    Casey Shannon.

  - Improved bounding behaviour with forceNetwork. Now bounds both the
    links and nodes. Thanks to Koba Khitalishvili.

                        Changes in version 0.2.7

    introduced in 0.2.4 for diagonalNetwork and radialNetwork.

  - sankeyNetwork gets same full margin control introduced in 0.2.4 for
    diagonalNetwork and radialNetwork.

                        Changes in version 0.2.5

  - More robust margin argument for diagonalNetwork and radialNetwork
    allows for a single value or specification of top, right, bottom,
    and left by named vector or list.

  - Responsive sizing using the viewBox attribute of svg for
    diagonalNetwork and radialNetwork should allow for fitting in the
    container with no fiddling.

0.2.3

  - Internal improvements to reduce dependencies: no longer depends on
    RCurl, plyr, and rjson.

  - Updated examples:

  - Using jsonlite makes JSONtoDF obsolete with the fromJSON function.

  - All Github data links now use the CDN link from rawgit, so the
    examples should be more inline with Github raw policies.

0.2.2

  - sankeyNetwork changes:
    
      - Removes forced font family in favor of inherited from css or
        specified through the fontFamily argument.
    
      - Fixes issue with backslashes in the label for links.
    
      - Puts unicode right arrow in the tooltip. Adds argument to
        specify units for the tooltip label.
    
      - Handles cycles by updating this forked repo:
        https://github.com/soxofaan/d3-plugin-captain-sankey.
    
      - Makes assumptions that Source is column 1 and Target is column 2
        if not provided.

0.2.1

  - Fixed an issue with forceNetwork on Firefox. Thanks to @agoldst.

  - Fixed an issue where forceNetwork node size would not return to
    default after mouseover. Thanks to Pascal Pernot.

0.2

  - Added dendroNetwork to create hierarchical cluster network diagrams
    (dendrograms).

  - treeNetwork is DEPRECATED.

  - Placed functionality from treeNetwork to radialNetwork. The new
    radialNetwork function has the same functionality, but has been
    renamed to be more accurately descriptive and avoid confusion with
    dendroNetwork.

  - Added diagonalNetwork, which creates tree network diagrams using
    diagonal instead of radial nodes.

Thanks to Jonathan Owen.

0.1.8

  - Added clickAction argument to forceNetwork to allow the user to pass
    a JavaScript expression through to be activated on click of a node.
    Thanks to Peter Ellis.

  - Added bounded argument to forceNetwork to allow the user to create a
    bounding box for the plot. See http://bl.ocks.org/mbostock/1129492.
    Thanks to Charles Sese.

  - Added fontFamily argument to forceNetwork, simpleNetwork,
    sankeyNetwork, and treeNetwork. Thanks to Peter Ellis.

  - Added opacityNoHover argument to forceNetwork to set the opacity of
    node labels when nodes are not hovered over. Thanks to Peter Ellis.

0.1.7

  - Include JS from htmlwidgets, to make it easier for users to pass
    arbitrary JS to more arguments.

  - Other internal code and documentation improvements.

0.1.6

  - fontSize used for all functions rather than fontsize. Thank you to
    @Hunter-Github for spotting this inconsistency.

0.1.5

  - Minor improvement to treeNetwork documentation. Thanks to Steven
    Beaupré and MrFlick.

0.1.4

  - forceNetwork gains three new arguments.
    
      - legend allows you to add a node colour legend.
    
      - radiusCalculation and Nodesize allow you to vary node radius by
        some values.

Thank you to Charles Sese for these additions.
