    Zipkin

    Zipkin

    Distributed tracing system to gather timing data

    Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data. If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration. Some interesting data will be summarized for you, such as the percentage of time spent in a service, and whether or not operations failed. The Zipkin UI also presents a Dependency diagram showing how many traced requests went through each application. This can be helpful for identifying aggregate behavior including error paths or calls to deprecated services. Applications need to be “instrumented” to report trace data to Zipkin.

    PlantUML

    Generate diagrams from textual description

    Generate UML diagram from textual description. PlantUML is not affected by the log4j vulnerability. The easiest way to test PlantUML is in an online solution that has PlantUML embedded, such as our online server. After testing, you may want to install PlantUML locally. Run (or have your software call) PlantUML, using sequenceDiagram.txt as input. The output is an image, which either appears in the other software, or is written to an image file on disk. Diagrams are defined using a simple and intuitive language. (see PlantUML Language Reference Guide). Images can be generated in PNG, in SVG or in LaTeX format. It is also possible to generate ASCII art diagrams (only for sequence diagrams).

    ChatterBot

    ChatterBot

    Machine learning, conversational dialog engine for creating chat bots

    ChatterBot is a Python library that makes it easy to generate automated responses to a user’s input. ChatterBot uses a selection of machine learning algorithms to produce different types of responses. This makes it easy for developers to create chat bots and automate conversations with users. For more details about the ideas and concepts behind ChatterBot see the process flow diagram. The language independent design of ChatterBot allows it to be trained to speak any language. Additionally, the machine-learning nature of ChatterBot allows an agent instance to improve it’s own knowledge of possible responses as it interacts with humans and other sources of informative data. An untrained instance of ChatterBot starts off with no knowledge of how to communicate. Each time a user enters a statement, the library saves the text that they entered and the text that the statement was in response to. As ChatterBot receives more input the number of responses that it can reply increase.

    draw.io

    draw.io

    JavaScript client-side editor for general diagramming & whiteboarding

    draw.io is a JavaScript, client-side editor for general diagramming and whiteboarding. draw.io, this project, is a configurable diagramming/whiteboarding visualization application. draw.io is jointly owned and developed by JGraph Ltd and draw.io AG. draw.io is a diagramming or whiteboarding application, depending on which theme is selected. It is not an SVG editing app, the SVG export is designed only for embedding in web pages, not for further editing in other tools. The application is designed to be used largely as-is. It's possible to alter the major parts of the interface, but if you're looking for an editor with very specific editing features, the project is likely not a good base to use. That is to say, if you wanted to create/deploy a whiteboard or diagramming application where the functionality in the main canvas is as this project provides, it is more likely to be a good base to use.

    D2

    D2

    D2 is a modern diagram scripting language that turns text to diagrams

    D2 is a diagram scripting language that turns text to diagrams. It stands for Declarative Diagramming. Declarative, as in, you describe what you want diagrammed, it generates the image. As well, the functioning of the install script is described in detail to alleviate any concern of its use. We recommend using your OS's package manager directly instead for improved security but the install script is by no means insecure. D2 includes a variety of official themes to style your diagrams beautifully right out of the box. See ./d2themes to browse the available themes and make or contribute your own creation. D2 is designed with language tooling in mind. D2's parser can parse multiple errors from a broken program, has an autoformatter, syntax highlighting, and we have plans for LSP's and more. Good language tooling is necessary for creating and maintaining large diagrams. D2 is designed to be extensible and composable.
