A Visualization Of The 100 Greatest Love Songs ft. D3.js

What would you do? If my heart was torn in two (More Than Words, Extreme)

Playing with rCharts package I had the idea of representing the list of 100 best love songs as a connected set of points which forms a heart. Songs can be seen putting mouse cursor over each dot. This is an screenshot of the graph:

HeartScreenshotIf you want to play with the visualization, you can download it here. Or better than this, you can reproduce it with this simple code:

heart <- function(r,x) {ifelse(abs(x)<2, ifelse(r%%2==0, sqrt(1-(abs(x)-1)^2), acos(1-abs(x))-pi), 0)} data.frame(x=seq(from=-3, to=3, length.out=100)) %>% 
  mutate(y=jitter(heart(row_number(), x), amount=.1)) -> df
love_songs <- html("http://www.cs.ubc.ca/~davet/music/list/Best13.html") love_songs %>%
  html_nodes("table") %>%
  .[[2]] %>%
  html_table(header=TRUE, fill = TRUE) %>%
  cbind(df) -> df
m1=mPlot(x = "x",  y = "y",  data = df,  type = "Line")
m1$set(pointSize = 5, 
       lineColors = c('red', 'red'),
       width = 850,
       height = 600,
       lineWidth = 2,
       hoverCallback = "#! function(index, options, content){
       var row = options.data[index]
       return '<b>' + row.ARTIST + '</b>' + '<br/>' + row.TITLE} !#",
m1$save('Top_100_Greatest_Love_Songs.html', standalone = TRUE)
