• new function to manage installation of Altair Python package: install_altair() (#1)

• makes Vega datasets available through import_vega_data() (#25)

• significant changes to the rendering function vegalite():

  • if the embed argument is NULL, vegalite() sets it to getOption("altair.embed_options") - if that is not defined, the vega-embed defaults are used

  • width and height arguments to vegalite() are used now to specify the total width and height of rendered charts - notes: (1) this is effective only for single-view charts, (2) width and height apply to the chart only, they do not take into account any action-links - if arguments are not set, the size of the chart is determined from the chart specification (#18)

  • vegalite() strips the style attribute from the <div/> for the htmlwidget - this has the effect of letting the rendered Vega-Lite chart determine the size of its container (#16, #18)

• adds concatenation operators for charts: |, &, + (#22, @aliciaschep)

• adds function vega_embed(), with friend only_actions(), to support embedding options in vegalite() (#16)
