Post Viewer and Analyzer with Go

Introduction

The Post Viewer and Analyzer is a web-based application built with Go. It serves a web interface that allows users to fetch posts from the JSONPlaceholder API, save these posts to a file, and perform a character frequency analysis on the saved data. This application demonstrates the use of Go for server-side web development, including handling HTTP requests, processing JSON, and rendering HTML templates.
