Show HN: Graph Visualization of Financial Correlations
observablehq.comAn attempt to show which financial products are highly correlated, negatively correlated, or non-correlated in an easily understood visual way.
Implemented using D3 force-layout, based on daily financial data generated by Google Sheet GOOGLEFINANCE function.
What's the name for this kind of graph is?
In mathematics, Graph Theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called links or lines).
This particular example shows a graph of financial tickers with links that represent the statistical correlation of their daily closing prices over a period of a year. Where the correlation number is between 1 and -1, with 0 being no correlation in either direction.

I know about the graph theory but it has many kinds of graphs. E.g. "directed acyclic graph" to name one. I don't yet know the actual Graph Theory do I don't know all the kinds and their names. So what I am asking about is what specific kind this graph is?
This is just a graph. Like water is just water. There is also salty water, and hot water, and cold water, but there is just water. This is just a graph, not any specific kind, simply a graph where you have nodes and links.
I mean I want to add the same in a WPF app so I need to know what to look for (just "graph" is too vague) to find either a library or some theory to help me in drawing it.
The code is available right there in Observable. You can look at the way the code takes the input data table and figure out how to replicate it somewhere else of your choosing.
