 Each series supports a set of options under `seriesOptions` and at minimum a string `label` is required for each series. An optional string `color` for can defined using either a variable name from the colors available in from the [zooniverse theme object](https://github.com/zooniverse/front-end-monorepo/tree/master/packages/lib-grommet-theme) or a hex value. If a color is not provided, a color from the zooniverse theme will be chosen and applied for each series. An optional `glyph` shape can be defined for the data series. This must be a string and must correspond to the following options: `'circle'`, `'cross'`, `'diamond'`, `'square'`, `'star'`, `'triangle'`, `'wye'`. If a glyph shape is not defined in the series options, then a fallback is automatically chosen based on the array order of the data series.
 
-The single series JSON shape is a very, very basic data object consisting of an array of numbers for each axis. The multiple series shape can also be used for a single series and is required if you need to use error bars:

 #### Chart Options
 
 For both single series data and multiple series data, a set of chart options can also be supplied that define the x-axis and y-axis labels as well as optionally the margins and padding to use and zoom configurations. Padding is defined as the space inside the axes lines. Defined padding will likely only be used by scatter plots using an inner tick direction similar to the current PH: TESS light curve viewer. Margin is defined as the space outside axes lines. Defined margin should be used by the outer tick direction which is the default orientation for the scatter plot axes.
