+# svg_fmt
+
+A set of simple types using `Display` formatters `{}` to easily write in the SVG format.
+This can be useful to dump information in a visual way when debugging.
+
+The crate is very small (and has no dependency).
+
+## Example
+
+```rust
+use svg_fmt::*;
+
+println!("{}", BeginSvg { w: 800.0, h: 600.0 });
+println!(" {}",
+ rectangle(20.0, 50.0, 200.0, 100.0)
+ .fill(Fill::Color(red()))
+ .stroke(Stroke::Color(black(), 3.0))
+ .border_radius(5.0)
+);
+println!(" {}",
+ text(25.0, 100.0, "Hi!")
+ .size(42.0)
+ .color(white())
+);
+println!("{}", EndSvg);
+
+```
