Freeze the Object prototype before rendering a chart: Object.freeze(Object.prototype)
Updating the chart then causes errors such as:
Uncaught TypeError: Cannot assign to read only property 'constructor' of object '#<Object>'

Possible solution

To prevent prototype pollution we freeze Object prototype. Chart.js is the only library we use that has an issues with that.

Expected behavior
Chart.js should be able to cope with Object prototype frozen. Object prototype constructor should not be reassigned.
Current behavior
The library attempts to reassign Object prototype constructor and thus breaks if Object prototype is frozen.
