Simplified library to output vector images in SVG format.

Implemented three types of objects:
- Circle
- Polyline
- Text
The color can be set as a string or rgb-values.
Method calls when creating Circle, Polyline, or Text objects can be chained. CRTP idiom is used. See /Transport_F.

Example

Svg::Document svg;

svg.Add(
    Svg::Polyline{}
    .SetStrokeColor(Svg::Rgb{140, 198, 63})  // soft green
    .SetStrokeWidth(16)
    .SetStrokeLineCap("round")
    .AddPoint({50, 50})
    .AddPoint({250, 250})
);

for (const auto point : {Svg::Point{50, 50}, Svg::Point{250, 250}}) {
  svg.Add(
      Svg::Circle{}
      .SetFillColor("white")
      .SetRadius(6)
      .SetCenter(point)
  );
}

svg.Add(
    Svg::Text{}
    .SetPoint({50, 50})
    .SetOffset({10, -10})
    .SetFontSize(20)
    .SetFontFamily("Verdana")
    .SetFillColor("black")
    .SetData("C")
);
svg.Add(
    Svg::Text{}
    .SetPoint({250, 250})
    .SetOffset({10, -10})
    .SetFontSize(20)
    .SetFontFamily("Verdana")
    .SetFillColor("black")
    .SetData("C++")
);

svg.Render(std::cout);
