Answer 1

I just created an example with the chart from the link. The main thing is that you have to call D3 code in the mounted() life-cycle hook of the Vue instance and you also need to have the SVG element in your <template>
Example with the same chart:
const jsonData = {"name":"variants","children":[{"name":"2","children":[{"name":"p23.3","children":[{"name":"IFT172","children":[{"name":"undefined","size":28},{"name":"aaaacxi7gjs3gascvqjaabaaaq","size":3},{"name":"aaaacxi7gjs3eascvqjaabaaci","size":6},{"name":"aaaacxi7gjs3gascvqjaabaabe","size":6},{"name":"aaaacxi7gjs3gascvqjaabaacm","size":1},{"name":"aaaacxi7gjs3eascvqjaabaaca","size":8},{"name":"aaaacxi7gjs3gascvqjaabaace","size":7},{"name":"aaaacxi7gjs3eascvqjaabaab4","size":5},{"name":"aaaacxi7gjs3gascvqjaabaaae","size":3},{"name":"aaaacxi7gjs3eascvqjaabaace","size":9},{"name":"aaaacxi7gjs3eascvqjaabaacq","size":9},{"name":"aaaacxi7gjs3gascvqjaabaaa4","size":4},{"name":"aaaacxi7gjs3eascvqjaabaaau","size":13},{"name":"aaaacxi7gjs3gascvqjaabaaay","size":5},{"name":"aaaacxi7gjs3eascvqjaabaaby","size":6},{"name":"aaaacxi7gjs3eascvqjaabaabq","size":5},{"name":"aaaacxi7gjs3gascvqjaabaaam","size":6},{"name":"aaaacxi7gjs3iascvqjaabaaaq","size":6},{"name":"aaaacxi7gjs3eascvqjaabaabi","size":5},{"name":"aaaacxi7gjs3iascvqjaabaaae","size":3},{"name":"aaaacxi7gjs3gascvqjaabaacu","size":2},{"name":"aaaacxi7gjs3eascvqjaabaabm","size":3},{"name":"aaaacxi7gjs3gascvqjaabaabu","size":3},{"name":"aaaacxi7gjs3iascvqjaabaaai","size":7},{"name":"aaaacxi7gjs3gascvqjaabaac4","size":3},{"name":"aaaacxi7gjs3gascvqjaabaabq","size":4},{"name":"aaaacxi7gjs3eascvqjaabaaay","size":6},{"name":"aaaacxi7gjs3gascvqjaabaabm","size":2},{"name":"aaaacxi7gjs3iascvqjaabaaa4","size":5},{"name":"aaaacxi7gjs3iascvqjaabaaau","size":7},{"name":"aaaacxi7gjs3gascvqjaabaabi","size":5},{"name":"aaaacxi7gjs3iascvqjaabaaba","size":12},{"name":"aaaacxi7gjs3iascvqjaabaaay","size":4},{"name":"aaaacxi7gjs3gascvqjaabaaca","size":6},{"name":"aaaacxi7gjs3gascvqjaabaacq","size":4},{"name":"aaaacxi7gjs3eascvqjaabaaa4","size":4},{"name":"aaaacxi7gjs3iascvqjaabaabi","size":5},{"name":"aaaacxi7gjs3iascvqjaabaabe","size":1},{"name":"aaaacxi7gjs3gascvqjaabaaci","size":4},{"name":"aaaacxi7gjs3gascvqjaabaaai","size":4},{"name":"aaaacxi7gjs3gascvqjaabaaba","size":2},{"name":"aaaacxi7gjs3gascvqjaabaada","size":1},{"name":"aaaacxi7gjs3eascvqjaabaabe","size":2},{"name":"aaaacxi7gjs3eascvqjaabaacm","size":5},{"name":"aaaacxi7gjs3gascvqjaabaaau","size":2},{"name":"aaaacxi7gjs3iascvqjaabaaam","size":1},{"name":"aaaacxi7gjs3eascvqjaabaaba","size":1},{"name":"aaaacxi7gjs3gascvqjaabaab4","size":3}]}]}]},{"name":"3","children":[{"name":"p21.31","children":[{"name":"CACNA2D2","children":[{"name":"aaaacxi7gjufoascvqjaabaafi","size":2},{"name":"undefined","size":1},{"name":"aaaacxi7gjufqascvqjaabaaae","size":2},{"name":"aaaacxi7gjufqascvqjaabaadu","size":1},{"name":"aaaacxi7gjufqascvqjaabaaee","size":2},{"name":"aaaacxi7gjufqascvqjaabaace","size":1},{"name":"aaaacxi7gjufqascvqjaabaaca","size":2},{"name":"aaaacxi7gjufqascvqjaabaad4","size":2}]},{"name":"LARS2","children":[{"name":"aaaacxi7gj6pmascvqjaabaag4","size":30},{"name":"aaaacxi7gj6pmascvqjaabaagy","size":9},{"name":"aaaacxi7gj6pmascvqjaabaaga","size":16},{"name":"aaaacxi7gj6pmascvqjaabaagq","size":8},{"name":"aaaacxi7gj6pmascvqjaabaahi","size":11},{"name":"aaaacxi7gj6pmascvqjaabaagm","size":14},{"name":"aaaacxi7gj6pmascvqjaabaage","size":1},{"name":"undefined","size":10},{"name":"aaaacxi7gj6pmascvqjaabaaia","size":12},{"name":"aaaacxi7gj6pmascvqjaabaahy","size":15},{"name":"aaaacxi7gj6pmascvqjaabaafq","size":8},{"name":"aaaacxi7gj6pmascvqjaabaaha","size":10},{"name":"aaaacxi7gj6pmascvqjaabaagu","size":12},{"name":"aaaacxi7gj6pmascvqjaabaaf4","size":10},{"name":"aaaacxi7gj6pmascvqjaabaahq","size":10}]}]}]},{"name":"7","children":[{"name":"q22.1","children":[{"name":"TFR2","children":[{"name":"aaaacxi7gjz4wascvqjaabaadq","size":2},{"name":"aaaacxi7gjz4yascvqjaabaaaq","size":1},{"name":"undefined","size":24},{"name":"aaaacxi7gjz4wascvqjaabaacq","size":4},{"name":"aaaacxi7gjz4yascvqjaabaaay","size":1},{"name":"aaaacxi7gjz4wascvqjaabaadm","size":1},{"name":"aaaacxi7gjz4wascvqjaabaacy","size":2},{"name":"aaaacxi7gjz4yascvqjaabaabi","size":2},{"name":"aaaacxi7gjz4yascvqjaabaaau","size":6}]}]}]},{"name":"9","children":[{"name":"q22.2","children":[{"name":"SECISBP2","children":[{"name":"undefined","size":30},{"name":"aaaacxi7gkabkascvqjaabaaea","size":9},{"name":"aaaacxi7gkabkascvqjaabaae4","size":6},{"name":"aaaacxi7gkabkascvqjaabaaf4","size":6},{"name":"aaaacxi7gkabkascvqjaabaaey","size":7},{"name":"aaaacxi7gkabkascvqjaabaafq","size":10}]}]}]},{"name":"12","children":[{"name":"q15","children":[{"name":"NUP107","children":[{"name":"undefined","size":16},{"name":"aaaacxi7gj74sascvqjaabaaby","size":10},{"name":"aaaacxi7gj74sascvqjaabaade","size":7},{"name":"aaaacxi7gj74sascvqjaabaadq","size":9},{"name":"aaaacxi7gj74sascvqjaabaab4","size":7},{"name":"aaaacxi7gj74sascvqjaabaacu","size":9},{"name":"aaaacxi7gj74sascvqjaabaaem","size":7},{"name":"aaaacxi7gj74sascvqjaabaaa4","size":3},{"name":"aaaacxi7gj74sascvqjaabaace","size":8},{"name":"aaaacxi7gj74sascvqjaabaaee","size":7},{"name":"aaaacxi7gj74sascvqjaabaady","size":3},{"name":"aaaacxi7gj74sascvqjaaba
