try vega, simplified api for d3

I think this will do the trick 

path.resolve(process.cwd(), 'fonts', 'NotoColorEmoji.ttf');

I'm generating the chart first as svg then blah blah blah

are you loading the fonts? and setting the chartset on the template? the entire frame cannot support lazyloaded fonts if it's done by d3 dynamically. you need to load it on the header.
