http://dopiaza.org/tools/datauri/index.php
provide text
no base64
specify mime type: image/svg+xml

build a template using pure svg:
<svg xmlns='http://www.w3.org/2000/svg'
width='1000px' height='500px' viewBox='0 0 200 100'>
<rect x='0' y='0' width='100%' height='100%' fill='white' />
<text x='0' y='20' font-family='monospace' font-size='6' fill='black'>
<tspan x='0' dy='1.2em'>Domain: https://boardroom.to</tspan>
<tspan x='0' dy='1.2em'>From: 0xabcdef</tspan>
<tspan x='0' dy='1.2em'>To: 0xfedcba</tspan>
<tspan x='0' dy='1.2em'>Value: 1.025 Ether</tspan>
<tspan x='0' dy='1.2em'>Gas: 0.025 Ether</tspan>
</text>
</svg>
or svg-embedded html:
<svg xmlns="http://www.w3.org/2000/svg" width="800" height="500">
<rect x='0' y='0' width='100%' height='100%' fill='white' />
<foreignObject class="node" x="46" y="22" width="200" height="300">
