Add a helper or mixin for handling common echarts data series data structures
Many of our charts will likely end up working on echarts' cartesian grid. Handling data series for these types of charts and common functionality like responsive resizing should be standardized as much as possible across multiple chart components.
Instead of having to duplicate the same implementation we should abstract as much of this as possible into reusable Vue or JS code so we can keep the code base DRY with a more centralized source of truth. The alternative will be ending up with many chart types that look almost exactly alike: line, area, column, stacked column, bar, stacked bar, for instance.
