"""
[Linechart2D] - General purpose node for Line Charts
A line chart or line plot or line graph or curve chart is a type of chart which
displays information as a series of data points called 'markers'
connected by straight line segments.
It is a basic type of chart common in many fields. It is similar to a scatter plot
except that the measurement points are ordered (typically by their x-axis value)
and joined with straight line segments.
A line chart is often used to visualize a trend in data over intervals of time –
a time series – thus the line is often drawn chronologically.
In these cases they are known as run charts.
