Process CSV/JSON files with stats summaries, correlations, normalization, and pivoting. Export to SVG and HTML. ## Commands ### `bar` Draw a horizontal bar chart from label:value pairs. ```bash scripts/script.sh bar "Sales:42" "Revenue:87" "Profit:31" ``` ### `histogram` Show frequency distribution of numeric values as a histogram. ```bash scripts/script.sh histogram 10 15 20 20 25 30 30 30 35 40 ``` ### `sparkline` Render an inline sparkline chart from a series of values. ```bash scripts/script.sh sparkline 4 8 15 16 23 42 38 29 18 10 ``` ### `heatmap` Display a color-coded heat grid from row/column data. ```bash scripts/script.sh heatmap 3 4 1 5 9 2 8 3 7 4 6 1 ``` ### `treemap` Show proportional blocks for part-to-whole comparisons. ```bash scripts/script.sh treemap "Chrome:65" "Safari:18" "Firefox:10" "Edge:7" ``` ### `gauge` Display a gauge meter showing a value against a maximum. ```bash scripts/script.sh gauge 73 100 "CPU Usage" ``` ### `matrix` Render a CSV file as a formatted matrix/table view. ```bash scripts/script.sh matrix data.csv ``` ### `summarize` Compute min/max/average/median statistics for each numeric column in a CSV file. ```bash scripts/script.sh summarize sales.csv ``` ### `distribution` Show the value distribution of numeric data in a CSV file across bins. ```bash scripts/script.sh distribution scores.csv 8 ``` ### `correlate` Compute a Pearson correlation matrix across all numeric columns in a CSV file. ```bash scripts/script.sh correlate metrics.csv ``` ### `normalize` Normalize all numeric columns to 0-1 range and output as CSV. ```bash scripts/script.sh normalize raw_data.csv > normalized.csv ``` ### `pivot` Group rows by a column and aggregate numeric values (sum, avg, min, max). ```bash scripts/script.sh pivot sales.csv region ``` ### `from-csv` Auto-visualize a CSV file with summary statistics. ```bash scripts/script.sh from-csv data.csv ``` ### `from-json` Auto-visualize a JSON file — shows structure, keys, and numeric column summaries. ```bash scripts/script.sh from-json data.json ``` ### `to-svg` Export CSV data as an SVG bar chart. ```bash scripts/script.sh to-svg sales.csv ``` ### `to-html` Export CSV data as an HTML table with styling. ```bash scripts/script.sh to-html report.csv ``` ### `help` ```bash scripts/script.sh help ``` ### `version` ```bash scripts/script.sh version ``` ## Examples ```bash # Quick terminal charts scripts/script.sh bar "Q1:120" "Q2:185" "Q3:210" "Q4:170" scripts/script.sh sparkline 10 20 30 25 40 35 50 45 scripts/script.sh gauge 78 100 "Memory" # CSV analysis pipeline scripts/script.sh summarize data.csv scripts/script.sh correlate data.csv scripts/script.sh pivot data.csv category # Export scripts/script.sh to-svg data.csv scripts/script.sh to-html data.csv ``` ## Configuration | Variable | Required | Description | |----------|----------|-------------| | `DATAVIZ_DIR` | No | Data directory (default: `~/.local/share/data-visualizer/`) | ## Data Storage History logged in `~/.local/share/data-visualizer/history.log`. ## Requirements - bash 4.0+ - python3 (for CSV processing, correlations, JSON parsing, SVG export) --- *Powered by BytesAgain | bytesagain.com | [REDACTED_SECRET]*
