Respecting your craft means using the right tools and techniques for the job. Not caring about one group of users is no excuse for needing Javascript to display a chart. You don't use Javascript to display a chart because you don't need Javascript to display a chart. Render the chart server-side and use an image to display it. It's a static chart, it's not like the information is changing with every page load. To do otherwise is just lazy and disrespectful.

Craft is not a personal conceit. You're thinking about art. And even then, most arts have a craft. Knowing your craft usually makes you a better artist, but is not strictly necessary.
