This example visualizes a system-administration script that automates the setup of an Ambari-managed Hadoop cluster. The code shows a sequence of shell commands and configuration steps, including disabling SELinux and iptables, installing Java and MySQL, and configuring databases and users. It uses the `awk` utility to edit `sshd_config` and the `mysql` command-line client to create and grant privileges on the `ambaridb`, `hivedb`, and `ooziedb` databases. The visualization maps the script’s control flow and dependencies, likely through a node-link diagram, to illustrate how each step builds on prior ones.

This visualization presents a server-stack installation script, not a typical data-driven graphic. It maps the procedural flow of an unattended Bash deployment of Ruby Enterprise and the Passenger Apache module, tracing each command and conditional branch as a node in a directed graph. The code uses a custom layout to arrange the script’s logic, with nodes representing commands like `sudo apt-get install` and `gem install`, while edges show the sequence and decision points (e.g., `if [ -e $REEF ]`). The rendering approach highlights the script’s structure, with color coding for installation steps versus error-handling exits, and the data source is the literal Bash code itself, parsed to extract control flow.

This example visualizes a system administration workflow that automatically masks or unmasksthe Linux sleep and suspend targets based on active SSH sessions. It shows a shell script that counts established SSH connections on port 22 using `ss` and `awk`, then conditionally runs `systemctl mask` or `systemctl unmask` on `sleep.target` and `suspend.target`. The visualization highlights the script’s branching logic driven by `PAM_TYPE` (open or close session) and the connection count. No external charting library is used; the code relies on standard shell utilities (`ss`, `awk`, `logger`, `sudo`) to manage systemd power management.

This example visualizes the installation steps for Node.js on Ubuntu using a procedural, code-driven diagram. It presents a sequence of terminal commands and system prompts as a branching flowchart, with nodes representing actions like `sudo apt install nodejs` and verification steps like `node -v`. The visualization uses D3.js to render the graph, likely employing `d3.forceSimulation` for node positioning and SVG elements for drawing links and labels. The code also relies on standard D3 selection and data-binding methods to map the command list into a structured network, highlighting the order and dependencies between installation phases.

This example visualizes a simple command-line workflow for extracting and executing archived files in Linux, showing tar and sudo commands in a terminal-style interface. The visualization uses D3.js to render the text output, likely employing `d3.select` and `d3.text` to load and display the command results. It presents a static, sequential display of terminal commands and their outputs, with no interactive elements beyond the initial rendering. The data is hardcoded as a plain text string containing the shell commands and their expected responses, and the code uses D3’s selection and text manipulation methods to place the content on the page.

This example shows a Bash script that installs Firejail and appends a set of filesystem blacklists to the `/etc/firejail/disable-common.local` configuration file. The code uses `apt-get` to update and install the `firejail` package, then checks if the local blacklist file exists before writing entries that deny access to sensitive paths such as `/etc/passwd`, `/etc/nginx`, and `/var/lib/mysql`. The script relies on shell redirection and a here-document to create the configuration content, with no visualization libraries or data sources involved.

This example demonstrates a step-by-step guide for installing Omeka on an AWS Lightsail instance, showing the process from logging in to connecting to the instance’s IP address. The instructions use a launch script fetched from a GitHub gist, which likely employs shell commands to automate the setup. The code relies on the AWS Lightsail web console for instance creation and the `curl` or similar command-line tool to retrieve the configuration script, though the exact libraries are not explicitly named. The visualization is textual, focusing on procedural clarity rather than graphical data, with the data source being the gist’s raw text file.

This example visualizes a custom workflow for managing development environment variables through a shell script. It shows how the script scans a directory for subdirectories, extracts their names, and dynamically sets environment variables pointing to those paths. The code uses standard Unix command-line tools like `ls`, `awk`, and shell `for` loops, along with `export` to define variables such as `dev` and `devwork`. No external visualization libraries are present; instead, the focus is on text-based configuration logic, with the output being variable assignments rather than graphical rendering. The data source is the local file system under `/Users/dylanfm/Development`.

The example shows a network visualization of tutorial links and resources for installing MariaDB/MySQL on Arch Linux, organized as a directed graph with nodes and curved edges. It uses D3.js, specifically `d3.forceSimulation` for layout and `d3.forceLink` for edge positioning, while nodes are rendered as circles with labels. The data comes from a hardcoded array of URL objects (e.g., dominicm.com, geekpills.com, tutofox.com) that define the connections between reference sites. The visualization arranges the nodes dynamically, with edges colored and opacity-scaled to indicate link direction, but does not include interaction or tooltips.
