I need to make a web calculator with 5 numer inputs and the result should be as in the attached images. The red & blue area should change its size based on the input values. Ususing a static background wont work, it must scale on certain input values as in the second image.
What would you use? CSS&javascript? I tried to convert the image to a carnvas without luck, I get 4megabytes of code and converting it to svg didn’t worked either I only the get the red poligon.
You can use Javascript to draw this quite easily. The link below should help you get started.
