Version 0.1
This project is based on the Sankey implementation in networkD3 and d3-sankey.
Changelog:
- ported to D3 v4
- based on https://github.com/d3/d3-sankey
- added several modifications from networkD3 sankey.js
- included fixes and features from unmerged pull requests:
- d3/d3-plugins#124: Fix nodesByBreadth to have proper ordering
- d3/d3-plugins#120: Added 'l-bezier' link type
- d3/d3-plugins#74: Sort sankey target links by descending slope
- d3/d3-sankey#4: Add horizontal alignment option to Sankey layout
- added option numberFormat, default being ",.5g" (see , fixes christophergandrud/networkD3#147)
- added option NodePosX, fixes christophergandrud/networkD3#108
- added option to force node ordering to be alphabetical along a path (only works well with trees with one parent for each node, but might fix christophergandrud/networkD3#153)
- zooming
- dragging both horizontally and vertically
The inst/examples/shiny web-app exposes several of the features:
