ggraph 2.2.0
Fix a precision bug in circle pack layout (#345)
GeomEdgeTile now uses edge_width instead
of edge_size for the border
Fix a bug in geom_edge_parallel() when used with edge
labels. Edges are now correctly offset, though label may still overlap
(#227)
Fix a bug with auto layout on undirected trees (#247)
Fix a bug in get_con() that would lead to wrong
matching of additional data (#249)
Allow na.rm in geoms (#301)
If check_overlap = TRUE in
geom_node_text() the rendering order is reversed so that
the top nodes are rendered, not the bottom ones
Updated guides to the new ggplot2 interface. For
guide_edge_direction(), this update adds the option to use
labels instead of an arrow using the labels argument.
create_layout() now returns a modified tibble rather
than a data.frame
The ... in get_nodes(),
get_edges(), and get_con() now accepts tidy
evaluation. get_nodes() and get_con() will get
evaluated on the node data in the original order (layouts may reorder
nodes), and get_edges() will get evaluated on the edge data
(#272)
The linear layout has gained a weight argument allowing
you to set how much space each node occupy. Further, the layout now
calculates statistics so that it can be used in conjunction with
geom_node_tile() and geom_node_arc_bar()
New layout added. Cactustree is a hierarchical layout optimised for
hierarchical edge bundling by placing nodes as budding circles on the
periphery of their parent (#226)

sorted in the from vector (#258)
ggraph 2.0.3
Fix bug in geom_edge_elbow() that resulted in
duplicated group columns in the data.
ggraph 2.0.2
Remove reshape2 dependency
ggraph 2.0.1
Fix bug in ggraph that will surface with the next grid release
Deprecate qgraph() in favour of
autograph() to avoid name collision with
qgraph::qgraph(). autograph() is now also a
generic with a default method, so you can provide your own specific
ggraph plot method for your network classes
ggraph 2.0.0
This release is a major release including many new features, bug
fixes and some breaking changes.
Breaking changes
Use tidygraph as the central data format. The results of this are
several:
All graph object supported by tidygraph are now supported on even
footing in ggraph. All layouts are now available to any graph class
BREAKING The "even" layout for
dendrograms are no more, but can be obtained by using the
"dendrogram" layout with height = NULL
BREAKING All layouts uses NSE for arguments that
refer to node and edge variables, instead of passing in strings that
refer to the variable name.
All examples and vignettes now uses tidygraph for graph manipulation
resulting in much cleaner code.
tree_apply has been removed in favour of using
tidygraph::map_bfs_*
geom_edge_elbow is no longer only available to
dendrogram objects
tidygraph algorithms can now be used directly within ggraph
functions. E.g. you can have sort.by = node_rank_hclust()
in your specification of a linear layout, or
aes(colour = group_infomap()) in node geoms
This big change fixes #21, #72, #79, and #81. A vignette has been
added to describe the integration in more detail
The curvature argument from
geom_edge_arc() and geom_edge_hive() as well
as the spread argument from geom_edge_fan()
has been deprecated in favor of the new strength
argument.
ggraph plots now gets constructed with grid and axes removed from
the default theme.
New features
Add equal-angle and equal-daylight unrooted tree layouts (#59)
Interface with the graphlayouts package and make all its layouts
available. The auto layout now uses the stress layout for standard
graphs (sparse stress) for larger graphs.
Added length argument to the dendrogram layout to allow the layout
to be based on edge length rather than node heights (#124).
Added geom_edge_parallel() for drawing multiedges as
parallel lines (#191)
Added fabric layout to create biofabric plots. Also added
geom_node_range() and geom_edge_span() for
visualising such layouts (#47)
Added geom_edge_bend() for drawing soft elbows
(#45)
Added geom_node_voronoi() for displaying nodes as
voronoi tiles (#100)
Added qgraph() for quickly creating a standard network
plot for explorative purpose (#94)
All non-straight line-based edge geoms now has a
strength parameter that controls their deviation from a
straight line. 0 will always give a straight line while
1 will be their natural look. Numbers outside this range
may look weird (#97)
Added weight and mode arguments to
get_con() that are passed on to the shortest path
calculations (#89).
Add matrix layout and geom_edge_point() (#23)
Added geom_edge_tile() for use with matrix layouts
(#141)
Manual layouts are now easier to specify. You can pass a matrix or
data.frame to the layout parameter that will then be used. Also, if an
x and y argument is present, the
auto layout will choose the manual layout.
(#91)
Custom layout functions are now much more flexible. And can either
return a data.frame or an object coercible to a
tbl_graph. In the latter case the node table will be used
as layout and the graph will be attached. This allows direct use of the
particles package as a layout engine as a side effect. (#88)
Bug fixes
Fixed numerous bugs and issues pertaining to the group aesthetic
handling in many edge geoms (#190, #193).
Edge geoms no longer throws an error when all edges are completely
capped (#176)
Fixed a bug that prevented edge capping from being used with *2
variants of edge geoms (#167)
Fix bug in edge capping that could lead to edges extending to (0,0)
(#163)
Fix bug affecting faceting of capped edges (#140)
Character aesthetics are no longer cast to factors in edge geoms
(#131)
Fix a bug where start capping was ignored if the previous edge had
been completely removed by capping (#150)
Fix offsetting bug in edge label drawing when some labels are empty
strings and label_parse = TRUE (#159)
Fixed a bug resulting in the wrong mapping of additional values to
connections (#122, #134)
Fixed a bug when using facet_graph() with data from
both tbl_df and data.frame
Added override.aes to
guide_edge_direction()
Fix bug with extracting edges from an empty graph (#76)
Fixed bug causing shifts in edge aesthetics when one or more edges
were completely clipped (#62, #115)
Fixed bug when clipping completely orthogonal points that produced
additional lines going to (0,0) (#70, #84, #103)
