apl pernafasan animasi pekeliling d3 js bergerak di laluan bulat

d3 js aplikasi pernafasan animasi

Saya mahu dapat mencipta animasi bulatan yang berputar mengelilingi laluan pada selang masa tertentu dan dapat mengawal selang itu untuk mempercepat/melambatkan.

Kod saya pada masa ini kelihatan seperti ini. Cara untuk menetapkan bulatan untuk bergerak di sepanjang laluan bulatan - dan juga minta bulatan induk itu sendiri "bernafas" masuk dan keluar

    Dapat mencipta apl ini menggunakan kod ini - tetapi mungkin perlu menjadikannya sebagai komponen tindak balas untuk menunjukkan/menyembunyikannya apabila pengguna mengklik butang main.
