G, thank you. Here is the code:
 
       library(igraph)
       D <- read.csv("New Jam.csv")
       D <- D[,-1]  
       G <- graph.adjacency(as.matrix(D), weighted=TRUE)


      V(G)$label <- V(G)$name
      V(G)$shape <- "rectangle"
      V(G)$color <- "white"
      V(G)$size <- 40

     
      mst <- minimum.spanning.tree(G)
      lay <- layout.reingold.tilford(G, mode="all")
     plot(mst, layout=lay)


 
Thanks again
