* feat(barchart): Add direction attribute Enable rendring the bars horizontally. In some cases this allow us to make more efficient use of the available space. Signed-off-by: Ben Fekih, Hichem <hichem.f@live.de> * feat(barchart)!: render the group labels depending on the alignment This is a breaking change, since the alignment by default is set to Left and the group labels are always rendered in the center.
