Add Chartifact dialog with automatic markdown to Chartifact conversion and CSS styling #1

Copilot · 2025-11-13T20:37:32Z

Chartifact Dialog Implementation ✅

Adds Chartifact functionality with automatic conversion of report markdown to Chartifact format, including CSS styling based on report type.

Changes Made:

✅ Removed "Chartifact" from report type toggle buttons
✅ Created separate ChartifactDialog.tsx component file
✅ Added "Create Chartifact" button next to "Share Image" button in report view
✅ Added textarea for report source in dialog
✅ Implemented automatic markdown to Chartifact conversion
✅ Added exportTableToDsv() utility function for CSV generation
✅ Reverted .gitignore changes (removed package-lock.json entry)
✅ Using Yarn for package management
✅ Reverted yarn.lock modifications (no lock file changes)
✅ Fixed image regex to match [IMAGE(chart-id)] format
✅ Added CSS styling based on report type (social post, executive summary, blog post)

Technical Implementation:

exportTableToDsv() in utils.tsx:

Uses d3.dsvFormat to properly convert table rows to DSV format
Handles escaping of special characters automatically
Reusable utility function

ChartifactDialog.tsx:

Contains generateStyleCSS() function that generates CSS based on report style:
- Social post/short note: Compact Twitter/X style with 520px max width, system font
- Executive summary: Professional serif font, 700px max width
- Blog post (default): Notion-like style with 800px max width, system font
CSS is prepended to Chartifact markdown as a code block
Contains convertToChartifact() function that:
1. Parses markdown for [IMAGE(chart-id)] tags (not markdown image format)
2. Looks up charts from store using chart ID
3. Retrieves table data from store using chart.tableRef
4. Generates Vega-Lite specs with named data sources
5. Exports table to CSV using exportTableToDsv()
6. Replaces [IMAGE(chart-id)] with vega-lite + CSV code blocks
7. Prepends CSS styling based on report type
Auto-converts on dialog open
Shows loading state during conversion
Textarea populated with Chartifact markdown

ReportView.tsx:

Passes reportStyle (generatedStyle) to ChartifactDialog
Passes necessary props to ChartifactDialog (charts, tables, conceptShelfItems, config)
"Create Chartifact" button simply opens dialog

Chartifact Format:

Following the examples in the chartifact/ folder:

\`\`\`css
body {
    max-width: 800px;
    margin: 20px auto;
    padding: 0 48px;
    font-family: -apple-system, BlinkMacSystemFont, "Segoe UI"...;
    color: rgb(55, 53, 47);
}
h1, h2, h3, h4, h5, h6 {
    color: rgb(37, 37, 37);
    font-weight: 700;
}
...
\`\`\`

Text content...

\`\`\`json vega-lite
{
  "$schema": "https://vega.github.io/schema/vega-lite/v6.json",
  "data": { "name": "chartData_chart123" },
  "mark": "bar",
  ...
}
\`\`\`

created with AI using Data Formulator

\`\`\`csv chartData_chart123
column1,column2,column3
value1,value2,value3
...
\`\`\`

Build Status:

✅ Successfully builds with yarn build

Lock Files:

✅ No modifications to yarn.lock

Please undo package-lock

@copilot let us not check in lock files for this PR.
Actually, let's not have a Chartifact option for report types (my bad). Instead, on the next screen where there is a Share Image button, let's have a Create Chartifact button there. This pops up the dialog. For now lets put the report "source" in a textarea on the dialog.
Also, lets have that dialog be its own file.

@copilot Great work! Now lets add a function to convert a given report's markdown to a Chartifact document.
Chartifacts are live reactive chart documents. But they are simple markdown. I've added a couple of examples in the chartifact folder. You will see that the function will only need to convert rendered images back to vega/vega-lite specs, and that you can append csv into the markdown. Do not worry about the style for now.
Once you have this function, when the Chartifact button is clicked, populate the textarea with the Chartifact markdown.

Implemented (commit bba79f1):

✅ Added exportTableToDsv() utility function using d3.dsvFormat
✅ Created convertToChartifact() function that:

Extracts chart-id from markdown images
Looks up charts from store using chart-id
Retrieves tables from store via chart.tableRef
Generates Vega-Lite specs with named data sources
Converts table data to CSV using the new utility
Replaces images with vega-lite + CSV code blocks

✅ Function moved to ChartifactDialog.tsx to keep ReportView clean
✅ Dialog auto-populates textarea with Chartifact markdown when opened
✅ Follows format from chartifact/ folder examples

The "Create Chartifact" button now converts the current report markdown to Chartifact format and displays it in the dialog's textarea.

@copilot I see [IMAGE(chart-1760743768741)] in the markdown and do not see the csv section

Fixed in commit 0b8a95b. The regex pattern was incorrect - it was looking for markdown image format ![alt](chart-id) but reports use [IMAGE(chart-id)] format. Updated the pattern to /\[IMAGE\(([^)]+)\)\]/g to correctly extract chart IDs and generate the vega-lite + CSV code blocks.

@copilot there is some conditional styling based on report type. We need to know the condition/report type so that we can style the chartifact accordingly. See the chartifact folder for an example of how to style with the css plugin. I imagine it will actually be simple. Also know that a chartifact is rendered in its own sandbox so you can also style the body tag.

@copilot there is some conditional styling based on report type. We need to know the condition/report type so that we can style the chartifact accordingly. See the chartifact folder for an example of ...

Implemented in commit ecc02bd. Added CSS styling based on report type:

Three style variations:

Social post/short note: Compact Twitter-style (520px max, system font, light blue accents)
Executive summary: Professional serif style (700px max, business colors)
Blog post (default): Notion-like style (800px max, neutral colors)

CSS is generated by generateStyleCSS() function and prepended to the Chartifact markdown as a CSS code block. The styling targets the body tag and common elements (headings, code, strong) since Chartifacts render in their own sandbox. The reportStyle is passed from ReportView to ChartifactDialog to determine which CSS to apply.
