PyPI Package Disguised as Instagram Growth Tool Harvests User Credentials

@ts-graphviz/core
Advanced tools
@ts-graphviz/core is a TypeScript library for creating and manipulating Graphviz graphs. It provides a programmatic way to build and render graphs using the Graphviz DOT language.
Creating a Graph
This feature allows you to create a directed graph, add nodes, and create edges between them. The `toDot` method converts the graph to DOT format.
const { digraph } = require('@ts-graphviz/core');
const g = digraph('G');
g.node('A');
g.node('B');
g.edge(['A', 'B']);
console.log(g.toDot());
Subgraphs
This feature allows you to create subgraphs within a main graph. Subgraphs can be used to group nodes together.
const { digraph, subgraph } = require('@ts-graphviz/core');
const g = digraph('G');
const s = subgraph('cluster_0');
s.node('A');
s.node('B');
g.subgraph(s);
console.log(g.toDot());
Graph Attributes
This feature allows you to set attributes for the graph, such as the direction of the graph layout.
const { digraph } = require('@ts-graphviz/core');
const g = digraph('G', { rankdir: 'LR' });
g.node('A');
g.node('B');
g.edge(['A', 'B']);
console.log(g.toDot());
The 'graphviz' package is a Node.js wrapper for the Graphviz command-line tool. It allows you to generate DOT files and render them to various formats like PNG, PDF, etc. Unlike @ts-graphviz/core, it relies on the Graphviz installation on your system.
The 'viz.js' package is a JavaScript port of Graphviz that runs in the browser and Node.js. It allows you to render DOT files directly in the browser without needing a Graphviz installation. It is more focused on rendering rather than programmatic graph creation.
The 'd3-graphviz' package integrates Graphviz with D3.js, allowing you to create and manipulate graphs using D3's data-driven approach. It is more suitable for dynamic and interactive visualizations compared to @ts-graphviz/core.
It is part of the ts-graphviz library, which is split into modular packages to improve maintainability, flexibility, and ease of use.
This package contains the core implementation of models and functions provided to users for the ts-graphviz library.
Import the necessary classes and functions from the @ts-graphviz/core package:
import { Graph, Node, Edge } from '@ts-graphviz/core';
Use the imported items in your project to create and manipulate DOT language elements:
const graph = new Graph('G');
const nodeA = new Node('A', { label: 'Node A' });
const nodeB = new Node('B', { label: 'Node B' });
const edge = new Edge([nodeA, nodeB], { label: 'A -> B' });
graph.addNode(nodeA);
graph.addNode(nodeB);
graph.addEdge(edge);
console.log(graph.toDot());
