Heat Map Graph

Heat Map Graph lets administrators build data heat maps backed by SQL SELECT queries on WordPress tables. Configure:

• Query: a single SELECT statement targeting WP tables
• Field mapping: row, column, and value fields produced by the query
• Color range: hex colors for min and max
• Status: enable/disable

Use the shortcode on pages/posts:

Security features: – Validates SQL is a single SELECT against WP tables only – Blocks DML/DDL keywords – No multiple statements – Admin-only UI with nonces and strict sanitization

On activation, two sample heat maps are created: – Posts per Day per Category (Last 30 Days) – Number of Post Tags per Category
