Basically whenever i open this page i need to add the script "D3.js". When i open the first time it all works right but if i change to another page and go back to this one, the script somehow doesn't load. I don't know, it seems like the "mounted" is executed only once. Im new to Vue.js anyway, thank you

const pagina2 = {
    template: `
    <div class="col-12 col-md-8">
       <article class="bg-dark text-white border border-dark rounded mt-4 mb-4">
           <h2 class="px-5 text-danger">Approfondimento Pagina 2</h2>
           <div id="d3-container"></div>
           <p class="px-5">Approfondimento</p>
