ngx-graph - Graph visualization library for angular

•    TypeScript

---

This library is focused on handling graph data (anything with nodes and edges) rather than chart data. Currently the only visualization uses the Dagre layout, which is specialized for directed graphs. The plan is to implement multiple visualisations for graph data within this same library. Eventually, ngx-charts-force-directed-graph may be imported into this library as another option to visualize your graph data. ngx-graph is a Swimlane open-source project; we believe in giving back to the open-source community by sharing some of the projects we build for our application. Swimlane is an automated cyber security operations and incident response platform that enables cyber security teams to leverage threat intelligence, speed up incident response and automate security operations.

react-native-pathjs-charts - Android and iOS charts based on react-native-svg and paths-js

•    Javascript

---

This library is a cross-platform (iOS/Android) library of charts/graphs using react-native-svg and paths-js based on the excellent work done by Roman Samec in the react-pathjs-chart library. The project is an early attempt at providing a ubiquitous solution for charts & graphs for React Native that offer a unified view across devices. Components include Pie charts, Bar charts, Smoothline charts, Stockline charts, Scatterplots, Tree graphs and Radar graphs. Since Paths-Js makes no assumptions about rendering, this library is perfect for using SVG path objects to render custom charts easily.

dash - Interactive, Reactive Web Apps for Python. Dash Is Productive™

•    Python

---

Build on top of Plotly.js, React, and Flask, Dash ties modern UI elements like dropdowns, sliders, and graphs directly to your analytical python code. Here’s a 43-line example of a Dash App that ties a Dropdown to a D3.js Plotly Graph. As the user selects a value in the Dropdown, the application code dynamically exports data from Google Finance into a Pandas DataFrame. This app was written in just 43 lines of code (view the source).

party-mode - An experimental music visualizer using d3.js and the web audio api.

•    Javascript

---

Using the web audio api, I can get an array of numbers which corresponds to the waveform of the sound an html5 audio element is producing. There's a good tutorial on how to do this. Then, using requestAnimationFrame (with a little frame limiting for performance reasons) I'm updating that array as the music changes. I then normalize the data a bit (or transform it slightly depending on the visualization) and redraw the screen based on the updated array. I'm using d3.js to draw and redraw SVG based on this normalized data. Each visualization uses the data a bit differently -- it was mostly trial and error to get some stuff I liked looking at. Since I'm using D3 -- which is just drawing SVG -- I was able to style everything in CSS (no images are used at all, including icons). There are a handful of differently colored themes for each visualization, and I do some rudimentary CSS namespacing by updating a class applied to the html element. eg. <html class='theme_1'>. This lets me override or substitute CSS rules pretty trivially. I can add some additional variation to each theme by messing with pseudo selectors. For example, I can use :nth-of-type to hide every nth SVG rectangle or making every odd child have a different stroke-dasharray, etc.

paths-js - Generate SVG paths for geometric shapes :bar_chart:

•    Javascript

---

Paths.js is a library to generate SVG paths, allowing you to create your own charts using a functional and testable API. It provides the primitives to create various shapes and charts starting from raw data, but it does not prescribe how you render these charts. This means you can use Paths.js to build components for your favorite frontend framework, and works even server-side on NodeJS. Paths.js offers three APIs, of increasing abstraction. The lowest level is a chainable API to generate an arbitrary SVG path. On top of this, paths for simple geometric shapes such as polygons or circle sectors are defined. At the highest level, there is an API to generate some simple graphs (pie, line chart, radar...) for a collection of data, assembling the simple shapes.
