What would be the most efficient approach with the least amount of
code? Should I convert the string to an array of objects, then work
with that?
Converting the string to a format required by Chart.js would be a necessary step. Chart.js does not accept csv as an input. The appropriate format varies by chart type (line, pie…)
For Google charts – see How to use Google Chart with data from a csv
Also, how do I create charts in google charts and chart.js with json
data?
For Chart.js, the documentation (http://www.chartjs.org/docs/#line-chart-introduction) has examples for each chart type to get you started.
The same for Google charts – https://developers.google.com/chart/interactive/docs/quick_start
