Known issues:
-
round hypotheekbedrag and woz to 500 precision
-
round interest to 0.05% precision
-
round hypotheekvorm to 5% precision
-
manual input of interest rates should accept e.g. 3.5 instead of 0.035
-
chart should appear at the top on smaller screen sizes, not on the bottom
-
eigenwoningforfait does not update when changing WOZ waarde
-
linear/annuity interest rates re-appear after hiding them, without touching the hypotheekvorm slider
-
overlap of input and slider on smaller screen sizes
-
reset button should be on top of the input field / blocks slider
-
no left margin on small screen
-
chart does not resize on smaller screens
Nice to haves:
-
add tests
-
compute optimal linear/annuity mix

Build on D3.js. The author's many examples proved a valuable resource. Amongst others: bisect mouseover.
