Breaking Changes

New sg_events function. Previously sigmajs sent all events to the server when in Shiny, this caused the whole visualisation to nearly crash when enabling edges events as too many events/too much data was sent to the server. You now need to specify which events you want to captur with sg_events. The shiny documentation has been changed to reflect those changes.

Minor

Overall install size reduced.

igraph object saved to speed up computations.
Added sg_scale_color to scale color according to node size.
sg_noverlap_p fixed.
sg_zoom_p added.
fixed many events callbacks.
sg_get_nodes_p and sg_get_edges_p added to retrieve nodes and edges from draw graph.
sg_drop_edges_p and sg_drop_nodes_p now function properly.
The filter family of functions has been reworked and sees the addition of the name argument as well as sg_filter_undo_p to undo fitlers (by name) as well as new functions to filter neightbours and more.
sg_clear added to clear the graph.
sg_change_*_p family added to change nodes and edges attributes on the fly.
Event improved.
sg_read_*_p family of functions to easily add nodes and edges in bulk.
sg_read_delay_*_p family of functions to easily add nodes and edges in bulk with a delay.

Add multiple buttons with sg_button.
sg_progress * sg_button make use of htmlwidgets function to prepend or append elements rather than the previous hacky way; improved performances.
Improved documentation.
Works in RStudio viewer.

sg_export split into sg_export_img and sg_export_svg.
Small bugfix where crosstalk key and group was not initialised in correct FUN.
Added support for button to trigger nodes and edges dynamic addition.
sg_get_layout returns nodes with coordinates rather than just the coordinates.
Graphs open in browser by default + warning is sent to console when using RStudio.
Added ability to trigger multiple events from the button.
Fixed bug in cluster and layout function where igraph would error on duplicate vertex name.
sg_neighbours now takes nodes and edges color as argument.

sg_layout added - layout graph using igraph package.
sg_get_layout added - helper to extract x and y coordinates, mainly for animations.
sg_cluster added - color nodes by cluster.
sg_get_cluster added - helper to get nodes color by cluster.
sg_button added - Add buttons to trigger events in static documents.
sg_export and sg_export_p added - To export the graph.
sg_progress added - show dynamic text.
sg_neighbours (& sg_neighbors) added - highlight neighbours on click.
sg_filter_gt_p and sg_filter_lt_p added - filter nodes, edges or both.

Functions added:

sg_force_stop - stops the forceAtlas2 layout after a given delay.
sg_force_start added, same as sg_force.
sg_add_nodes, sg_add_edges - Add nodes or edges to a static graph.
drop_nodes_delay_p, drop_edges_delay_p Proxy to drop nodes or edges with a delay.
drop_nodes_delay, drop_edges_delay Drop nodes or edges with a delay.

Initial version including all plugins and Shiny proxies.
