tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.

Readme
This is a plugin for Highcharts to display contour curves.
It extends the existing heatmap module (which you must include) to display smooth gradients that interpolate the data points, and optionally contour lines over it.
It can use either a list of discrete data points or a math function as an input.
If you specify a discrete list of points, the surface can be triangulated in 3 ways:
grid_width
data points.This is the same demo you can find for Highcharts Heatmap, but chart type was changed to 'contour', and you can toggle contour lines on each axis.
Note that it automatically uses Delaunay for triangulation, no extra effort required ;)
This demo uses the built-in suport for evaluating a dataFunction
: The points are evaluated in a regular grid and produce a 2D chart.
Extras:
This example augments the 2-D Curve Plot demo with extra axes that display the values of the contour curves.
This is equivalent to the 2-D Curve Plot demo, in 3D.
On this example, Both Y and Color axes store the same values, a trick that makes visualization easier.
Similar to the previous demo, but Y and Color axes have independent values.
This demo plots a radial function, but the locations of the data points are spread randomly.
You can create a good chart even when you cannot sample your data in a rectangular grid
This demo uses random data to show that your points don't need to make sense to create pretty chart :P
This is a just-for-fun extra: Since this plugin can draw surfaces in 3D, why not use it to render the Utah Teapot from an OBJ file?!
