Plots a graph in a spirical fashion, highly connected nodes are placed at center.

## S3 method for class 'spiral.graph'
plot(x, tp=61, vertex.color=NULL, 
color.random=FALSE, rank.function=NULL,tkplot=FALSE,
v.size=2, e.size=.5,e.curve=.5, v.lab=FALSE, bg="black",
e.col="grey", skip=0, ...)

`x`	`x` is a graph object created from an adjacency matrix or from a tabular data of two columns using `graph()` function available in `igraph`
`tp`	is a numeric value, a tuning parameter to get different spirical shapes.
`color.random`	is alogical value, if TRUE, picks colors randomly and assign to nodes depending on their degree
`rank.function`	is a 'function' class returns a two column matrix with number of rows equal to the total nodes in the graph.
`tkplot`	it is a boolean variable, if it is true, function will use 'tkplot' function to plot a graph, if it is false function will use plot function with the black background.
`v.size`	is a numeric value or a numeric vector which contains numeric values to assign the size of nodes.
`e.size`	is a numeric value to assign the width to edges.
`e.curve`	is a positive numeric value that adjusts the curvature of the edges.
`v.lab`	is a logical value to show vertex label.
`bg`	name of a color or a hexadecimal code of a color. This option is used to color the background of the plot. The default option is "black".
`e.col`	is a character or a hexadecimal color value to set the color of edges.
`vertex.color`	is a vector of colors assign colors to nodes depending on their degree, from high to low.
`skip`	is an integer value to plot nodes away from the center.
`...`	`...` parameter for other inputs.

This layout function plots network in a spiral fashion.

returns a list object of 'netbiov' class
