uPlot - 📈 A small, fast chart for time series, lines, areas, ohlc & bars

•    Javascript

---

μPlot is a fast, memory-efficient Canvas 2D-based chart for plotting time series, lines, areas, ohlc & bars; from a cold start it can create an interactive chart containing 150,000 data points in 135ms, scaling linearly at ~25,000 pts/ms. In addition to fast initial render, the zooming and cursor performance is by far the best of any similar charting lib; at ~35 KB, it's likely the smallest and fastest time series plotter that doesn't make use of context-limited WebGL shaders or WASM, both of which have much higher startup cost and code size. However, if you need 60fps performance with massive streaming datasets, uPlot can only get you so far. WebGL should still be the tool of choice for applications like realtime signal or waveform visualizations: See danchitnis/webgl-plot, huww98/TimeChart, epezent/implot, or commercial products like LightningChart®.

muze - Composable data visualisation library for web with a data-first approach now powered by WebAssembly

•    Javascript

---

Muze is a free data visualization library for creating exploratory data visualizations (like Tableau) in browser, using WebAssembly. It uses a layered Grammar of Graphics (GoG) to create composable and interactive data visualization for web. It is ideal for use in visual analytics dashboards & applications to create highly performant, interactive, multi-dimensional, and composable visualizations. It uses a data-first approach to define the constructs and layers of the chart, automatically generates cross-chart interactivity, and allows you to over-ride any behavior or interaction on the chart.

urban-informatics-and-visualization - Urban Informatics and Visualization (UC Berkeley CP255)

•    Jupyter

---

This is a hands-on course that trains students to analyze urban data, develop indicators, and create visualizations and maps using the Python programming language, open source tools, and public data. The course will first introduce the fundamentals of programming in Python before moving on to a survey of data analysis/visualization tools and technologies. Classroom sessions will include lectures and workshops. A series of exercises will reinforce the skills and topics being presented, and a final project will provide an opportunity for students to develop a more complete project from harvesting data from Open Data portals to synthesizing and analyzing those data to explore a question or problem, to communicating their results in a web map and blog, as well as a final presentation. This course is designed to provide future city planners with a toolkit of technical skills for quantitative problem solving. It requires some tolerance for experimentation, self-directed trial and error, and an interest in learning to write code. If you are willing to roll up your sleeves and embrace some uncertainty, you'll learn the fundamentals of urban data analysis and visualization, and might discover an entirely new lens through which to study, plan, and design neighborhoods, cities, and regions.

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.

•    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.
