-`e_bar` lets you pass `serie` (from your initial data.frame) which corresponds to `value` in the [original library](https://ecomfe.github.io/echarts-doc/public/en/option.html#series-bar.data). However the latter also takes, `label`, `itemStyle`, and `tooltip` but being JSON arrays they translate to lists in R and dealing with nested data.frames is not ideal. `e_add` remedies to that. It allows adding those nested data points.

 However, we can also set options specific to each timestep with `e_timeline_serie`. The arguments to this function differ quite a bit from the rest of the package. As we have to assign options to multiple timesteps at once we need to pass vectors or lists of options, the length of the timesteps.
