d3.js, multiple script tags blocking eachother-CodePudding

I am new to JavaScript and HTML, and am writing my first webpage. I want to insert two different visualisations made with d3.js (which each have different .js files) in my html file. The second is not rendering and seems to be blocked by the first. Here is the html where I source them:

<body>
.....
<script src="js/d3_basic_bar.js"></script>
<script src="js/d3_basic_scatter.js"></script>
</body>

The first visualisation associated with d3_basic_bar.js is rendering, but the second isn't, how can I get both to render on the page?

Thanks

Since been resolved, common variables blocked each script from running concurrently.
