answer browsers not show similar behaviour svg. in chrome adding svg element directly using below statement work well

var svg = objdivtoaddtosvg.innerhtml; 

on firefox,

var svg = '<svg viewbox = "-50 -50 ' + (maindiv.width*2) + ' ' + (maindiv.height*2) + '" width="' + maindiv.width + '" height="' + maindiv.height + '">' + objdivtoaddtosvg.innerhtml + '</svg>'; 

maindiv <div> element wrapping around svg.

svg containing data being converted image. image can seen in chrome without settings. in firefox, svg attributes viewport , viewbox needs specified let browser know svg dimensions.

for information viewport , viewbox please follow link

in above code firefox, viewport , viewbox specified follows: 1) viewport - using height & width properties 2) viewbox - using

viewbox = "-50 -50 ' + (maindiv.width*2) + ' ' + (maindiv.height*2) 

i.e. viewbox = x y min-height min-width

for other browsers (tested opera , safari; not tested on ie)

var svg = objdivtoaddtosvg.innerhtml;
