Graph View

Data visualisation terminal — chart commands, git stats, and BERT NLP analysis.

Overview

Graph View is a large, specialised terminal (approximately 7,400 lines of code) dedicated to data visualisation, git history analytics, and BERT-powered NLP classification. Unlike Dev Hub or Security Hub, Graph View has its own command parser (parseChartCommand), its own log system, and its own Canvas Terminal sub-component for node/workflow visualisation.

Because of its size and specialised purpose, Graph View is a fully standalone module. Commands and block types from other terminals do not cross over into Graph View, and vice versa.

Standalone Module — Do Not Mix Commands

Graph View commands (chart bar, bert-classify, git-stats) are only available inside Graph View. They cannot be used in Dev Hub Terminal or Security Hub. Similarly, Dev Hub commands like analyze-performance are not available in Graph View.

Chart Commands

The core of Graph View is its chart rendering engine. Type a chart command and the terminal renders an interactive chart inline in the session.

Command	Chart Type	Example
chart bar [dataset]	Bar chart	chart bar sales-by-month
chart line [dataset]	Line chart	chart line revenue-trend
chart pie [dataset]	Pie / donut	chart pie market-share
chart scatter [dataset]	Scatter plot	chart scatter user-cohorts

Charts are rendered interactively — hover over data points to see values, click legend items to toggle series. Charts can be exported as PNG from the chart context menu.

Git Stats

Graph View integrates with gitStatsService.ts to fetch live git history data and render it as charts. These commands are also available in Terminal Editor but not in Dev Hub or Security Hub.

Command	Description
git-stats commits-by-author	Bar chart showing commit count per contributor
git-stats file-changes-over-time	Line chart of file modification frequency over the past 90 days
git-stats commits-per-week	Bar chart of weekly commit volume
git-stats top-files	Horizontal bar chart of most frequently changed files

BERT NLP Analysis

Graph View includes a local BERT model for text classification. Use the bert-classify command to run intent and category classification on any text input. The result is rendered as a probability distribution chart showing confidence scores per class.

Command	Description
bert-classify "[text]"	Classify the text using the local BERT model. Returns a bar chart of class probabilities.
bert-classify --batch [file]	Classify each line of a text file and aggregate results into a summary chart.

BERT Runs Locally

BERT classification uses a locally-loaded model — no API key required and no data leaves your machine. This makes it suitable for classifying sensitive documents. Note that local BERT is for classification only; it does not generate text.

Canvas Terminal

Inside Graph View, there is a sub-terminal called Canvas Terminal dedicated to node and workflow visualisation commands. Canvas Terminal uses only TextBlock — it does not use Run, Pipe, Select, or Diff blocks.

Canvas Terminal is useful for rendering the topology of a workflow you've built in the Workflow Editor, or for visualising dependency graphs and data flow diagrams using simple text-based commands.

Important Notes

Graph View has its own dedicated log system separate from the shared useTerminalState hook used by other terminals.
The parseChartCommand parser is unique to Graph View — it understands chart-specific syntax that the shared commandParser.ts does not handle.
If you need chart rendering in a different terminal session, use Terminal Editor which also supports ChartView inside TextBlocks.
Graph View is the only terminal where git-stats commands are available alongside chart commands in the same session — ideal for repo health dashboards.
