Chart Generator Zc

Data visualization tool producing SVG charts. Use when you need bar charts, line charts, pie charts, tables, sparklines, gauges,.

Security Scan

The skill's code, instructions, and resource use are consistent with a local chart-generation utility that writes SVG/HTML/ASCII output; nothing in the bundle indicates network exfiltration or unrelated credential access, though there are metadata inconsistencies and it writes files to disk.

Purpose & Capability

Name/description promise SVG/ASCII charts and the provided scripts (scripts/chart.sh and scripts/script.sh) implement exactly that: ASCII charts, SVG/HTML exports, CSV import, and a history log. The tool requests no external credentials and no unexpected binaries.

Instruction Scope

SKILL.md instructs running scripts/chart.sh and describes the data formats. The runtime scripts create files (SVG/HTML) and a history log, read CSV files when asked, and respect CHART_DIR/XDG_DATA_HOME/HOME for storage. They do not call external network endpoints. This is within scope, but be aware the skill writes to the user's filesystem and reads CSV files you point it to.

Install Mechanism

No install spec — instruction-only with bundled scripts. No remote downloads or installers; lowest-risk install model.

Credentials

No required environment variables or credentials are declared. Scripts optionally honor CHART_DIR and XDG_DATA_HOME (common location vars) and use HOME for defaults. These are proportionate to a file-writing chart tool.

Persistence & Privilege

The skill is not always-enabled and can be invoked by the user. It creates a data directory (defaults to $XDG_DATA_HOME or $HOME/.local/share/chart-generator) and appends to a history.log — expected for this app but worth noting if you want to avoid persistent files.

Assessment

This skill appears to do what it says: generate ASCII and SVG/HTML charts locally. Before installing or running it: (1) expect it to create files (SVGs, HTML, and a history.log) under $CHART_DIR or $XDG_DATA_HOME (defaults to ~/.local/share/chart-generator); (2) it accepts CSV file paths you provide — only give it non-sensitive CSVs unless you trust the code; (3) there are minor metadata/version mismatches in the bundle (registry vs _meta.json vs SKILL.md) and a few sloppy shell idioms, so you may want to run it in a sandbox/container or review the scripts yourself; (4) if you need networked or credentialed behavior, this skill does not provide it. If you want extra caution, run chart commands on test data and inspect created files before using on production data.

Chart Generator

数据可视化图表生成器，通过 scripts/chart.sh 生成ASCII图表或HTML文件。

为什么用这个 Skill？ / Why This Skill?

• 即开即用：一条命令直接出图，不需要安装matplotlib、echarts等复杂依赖
• 双输出：终端ASCII图表（方便命令行查看）+ HTML文件（方便分享和嵌入）
• 迷你趋势图：Unicode sparkline一行搞定趋势展示
• Compared to asking AI directly: produces actual runnable chart output (ASCII art + HTML files), not just code snippets you'd need to run yourself

使用方式

脚本路径：scripts/chart.sh（相对于本skill目录）

数据格式

• 键值对: "标签:数值,标签:数值" — 用于 bar, pie, html-bar
• 纯数值: "1,5,3,8,2,7" — 用于 line, sparkline
• 表格: "列头1,列头2|行1值1,行1值2|行2值1,行2值2" — 管道符分隔行，逗号分隔列

选项

• --title "标题" — 图表标题（bar, line, pie）
• --output file.html — HTML输出文件路径（html-bar）

输出示例 / Example Output
