After rendering after effects file to data.json and lottie.js file even I add script and linked lottie file in website animation doesn't show up but in demo it comes. Can you folks check whether I have done some thing wrong with the coding.

<script src="lottie.js"></script> 
<script>
var animation = bodymovin.loadAnimation({
    container:document.getElementById('bm'),
    renderer:'svg',
    loop: true,
    autoplay:true,
    path:'data.json'
})
</script>
