# Create an Interactive Chord Diagram in R

The `chordViz` package, based on the `chorddiag` package (http://github.com/mattflor/chorddiag) and

the viz.js D3 library (http://github.com/NPashaP/Viz), is an R htmlwidget that allows the user to create

interactive chord diagrams that emphasize the clarity of directed relationships

between groups on hover/mouseover.

## Example

```r

# Install and load package.

devtools::install_github("nredell/chordViz")

library(chordViz)

# Create an input matrix with random data.

set.seed(224)

m <- matrix(trunc(runif(100, 1, 20)), nrow = 10)

# Create the chord diagram.

chordViz(m, start = 3/2, groupNames = LETTERS[1:ncol(m)])

```
