mouseover: show picture on center circle at the same

[Jolanta Paliszewska]

I would like to insert that it should be to show data on mouseover of circle with pictures from the file. How can I load an image from a JSON array in this script? How I can add the pictures.

var data = [
{
 "str_lab": „A“,
 "num": 300,
„image: “graphics/a.svg"
},
{
 "str_lab": „B“,
 "num": 44,
„image: “graphics/b.svg"

},
{
 "str_lab": „C“,
 "num": 215,
„image: “graphics/c.svg"
},
{
 "str_lab": „D“,
 "num": 30,
„image: “graphics/d.svg"
} ];
