Datatable to barchart without images, libraries or plugins

Following the results of a survey on library use by developers I was asked to make it easier to do a head to head comparison of the data of one of the questions. I thought it’d be interesting to start a dynamic bar chart from scratch and it is incredible just how easy these things are nowadays.

The code is available on GitHub and you can see it in action there, too.

Check the code comments to see what I did – there is no magic in there, just using what browsers give us these days.

There is a bit more to it as I explain in this Screencast on YouTube:

If you don’t want the barcharts to show up but check if meter or progress is supported instead, add a parameter to the URL:

This is an interesting little demo as you’d probably be tempted to use meter from the get-go, but thinking about the data here makes a data table the best starting point.
