A Python command-line tool for creating text-mode diagrams using UTF-8 characters and color palettes.
Diagram is a Python-based tool for creating text-mode diagrams using UTF-8 characters and color palettes. It generates visual representations like axis graphs and bar charts directly in terminals or text files, solving the need for lightweight, portable data visualization without graphical dependencies.
Developers, system administrators, and data analysts who work in terminal environments or need to embed diagrams in text-based reports, logs, or documentation.
It offers a unique, dependency-free approach to visualization by using text and colors, making it ideal for scripting, remote servers, or any scenario where graphical libraries are impractical.

Runs without graphical dependencies, using UTF-8 characters for output in any terminal or text file, ideal for server environments. Evidence: README describes it as 'text mode diagrams using UTF-8 characters.'
Supports 16 and 256 color modes with pre-defined palettes like spectrum, grey, and RGB variants, enhancing visual appeal in terminals. Evidence: README lists 'Supports both 3 bit (16 color) and 8 bit (256 color) mode colors with various pre-defined palettes.'
Includes logarithmic scaling and Savitzky-Golay filtering for smoothing data, adding analytical depth to basic graphs. Evidence: Usage section describes '-f function' for 'log' and 'smooth' operations.
Can operate in batch mode for automated diagram generation, useful for scripting and report automation. Evidence: Command-line option '-b, --batch' enables batch mode with sleep intervals.
Only supports axis graphs and bar graphs; lacks common charts like scatter plots, pie charts, or heatmaps, restricting versatility. Evidence: Features list specifies only 'Axial graphs' and 'Horizontal and vertical bar graphs.'
Requires specific system libraries like ncurses-devel on Fedora, complicating installation on some platforms. Evidence: README includes 'System requirements for Fedora Core 24: dnf install ncurses-devel ncurses-compat-libs.'
Build status badges link to deprecated services (Travis CI), suggesting potential lack of recent updates or community activity. Evidence: Badges in README point to travis-ci.org and landscape.io, which are outdated.
