Fast SVG in Elm
Scalable vector graphics (SVG) is a way to display lines, rectangles, circles, arcs, etc.
The API is a bit wonky, but (1) it is manageable if you look through MDN docs like these and (2) you can attach event listeners to any shapes and lines you create!
import Svg exposing (..) import Svg.Attributes exposing (..)
main = svg [ width "120" , height "120" , viewBox "0 0 120 120" ] [ rect [ x "10" , y "10" , width "100" , height "100" , rx "15" , ry "15" ]  , circle [ cx "50" , cy "50" , r "50" ]  ]
I highly recommend consulting the MDN docs on SVG to learn how to draw various shapes!
SVG is great for data visualizations, and I really want people in the Elm community to explore more in that direction! My instinct is that functions like
view : data -> Svg msgwill be way easier to work with than what is available in other languages. Just give the data! No need to have data and interaction deeply interwoven in complex ways.
So if you are interested in doing something like this, I recommend:
In other words, try to learn as much as possible first! Anyone can show dots on a grid, but a great package will build expertise into the API itself, quietly leading people towards better design and accessibility. Ideally it will help people learn the important principles as well, because it is not just about getting data on screen, it is about helping people understand complex information!
This package should only change to account for new SVG tags and attributes.
