Hi praveenrongali , In addition to Poojara_D12  response, i am adding some more points and Microsoft learning documents.

Power BI Training Offers structured learning paths for Connecting and transforming data using Power Query, Modeling data with DAX, Building visuals and reports.

Please follow below things, Best Practices for Big Data & Performance Optimization:

1. Use star schema with clear fact/dimension separation. Avoid bi-directional relationships unless necessary.

2. Apply filters early in Power Query. Use incremental refresh and query folding.

3. Reduce clutter, embrace white space, and use bookmarks for user storytelling.

4. Use 64-bit Power BI Desktop and allocate sufficient memory.

Please refer below to Create Custom Visuals in Power BI:

1. Use the Package visuals as .pbiviz files.

2. Use the Tools & Libraries, powerbi-visuals-api for lifecycle hooks and lodash, moment for rendering and utilities. HTML Viewer and Deneb for advanced visuals.

3. Use private class properties for persistent elements like svg, host. Use AppSource for PBI certified community visuals.
