MDV (Markdown Data & Visualization) is a powerful Markdown superset designed for creating documents, dashboards, and slides with integrated data and visual content. It enhances standard Markdown with a set of features that allow for the easy incorporation of charts, KPI cards, tables, and styled regions without the need for complex coding or expressions.

Key Features

• YAML Front-Matter: Define your documents with metadata including titles, themes, and dataset references.
• Fenced Blocks for Data Visualization: Leverage fenced code blocks to insert various types of data visualizations. For example:

  ```chart type=bar x=region y=sales```
  

• Stylized Regions: Use ::: containers for creating styled sections within your documents, such as callouts or columns.
• Automatic Table of Contents: Generate an organized table of contents effortlessly with the ::: toc functionality.

Example Usage

Here is how a typical MDV file looks:

---
title: Q1 Report
theme: report
data:
  sales: ./data/sales.csv
---

::: toc
:::

# Q1 Results

```stat
label, value, delta
Total revenue, $2.06M, +14%
New customers, 1238, +8%
```

```chart type=line data=sales x=month y=revenue series=region yFormat=currency title="Monthly revenue"
```

This snippet showcases a flash report featuring a table of statistics and a line chart visualizing monthly revenue, both rendered seamlessly in a self-contained HTML format or as a PDF.
