svg.tag :rect, x: 5, y: 6


# 4. Using #build
svg.build do
  rect x: 0, y: 10
  circle cx: 10, cy: 10

# Nesting

Ruby Input

SVG Output

# 1. Using a block
svg.g transform: 'translate(10 10)' do
  svg.rect x: 10, y: 10
end

# 3. Using tag-less node
svg.build do
  text font_family: 'Roboto' do
    _ 'Hello'
  end
end

<!-- 1 -->
<g transform="translate(10 10)">
