## 🚀 Features

- **📥 CSV Parsing**: Effortlessly parse CSV files into JavaScript objects.
- **🧹 Data Cleaning**: Remove duplicates, fill missing values, and ensure data integrity.
- **📊 Data Analysis**: Perform various statistical analyses including averages, totals, and custom calculations.
- **📈 Data Visualization**: Create dynamic plots and graphs to visualize your data clearly.
- **📝 Documentation**: Comprehensive documentation with examples for easy integration.

## 🔗 Installation

To install the package, run the following command in your terminal:

```bash
npm install @private.ankit047/data-analyzer

🛠️ Usage

Here's a quick example to get you started with Data Analyzer. The example covers the entire workflow from parsing a CSV file to visualizing the analysis results.

Step 1: Parsing a CSV File

First, you need to parse a CSV file into JavaScript objects. This can be done using the parseCSV function.

const { parseCSV } = require('@private.ankit047/data-analyzer');

// Parse a CSV file
async function loadData() {
    const data = await parseCSV('path/to/your/file.csv');
    console.log(data);
}

loadData();

Step 2: Cleaning the Data

Once you have the data parsed, you may want to clean it to ensure it's ready for analysis. The cleanData function provides options for removing duplicates and filling in missing values.

const { cleanData } = require('@private.ankit047/data-analyzer');

async function cleanAndPrepareData() {
    let data = await parseCSV('path/to/your/file.csv');
    const cleanedData = cleanData(data, { removeDuplicates: true, fillMissing: 0 });
    console.log(cleanedData);
}

cleanAndPrepareData();

Step 3: Analyzing the Data

With cleaned data, you can now perform analysis using the analyzeData function. This function can compute various statistics such as averages, sums, and more.

const { analyzeData } = require('@private.ankit047/data-analyzer');

async function analyzeCleanedData() {
    let data = await parseCSV('path/to/your/file.csv');
    const cleanedData = cleanData(data, { removeDuplicates: true, fillMissing: 0 });
    const analysisResults = analyzeData(cleanedData);
    console.log(analysisResults);
}

analyzeCleanedData();

Step 4: Visualizing the Results

Finally, you can visualize the analysis results using the plotData function. This allows you to create charts and graphs to better understand the data.

const { plotData } = require('@private.ankit047/data-analyzer');

async function visualizeAnalysis() {
    let data = await parseCSV('path/to/your/file.csv');
    const cleanedData = cleanData(data, { removeDuplicates: true, fillMissing: 0 });
    const analysisResults = analyzeData(cleanedData);
    plotData(analysisResults);
}

visualizeAnalysis();

📜 API Reference

1. parseCSV(filePath: string): Promise<Object[]>

• Description: Parses the specified CSV file and returns an array of objects.
• Parameters:
  • filePath: The path to the CSV file (must be a valid file path).
• Returns: A promise that resolves to an array of parsed objects.
• Example:

  const data = await parseCSV('data/sample.csv');

2. cleanData(data: Object[], options: Object): Object[]

• Description: Cleans the input data based on the specified options.
• Parameters:
  • data: An array of objects to be cleaned.
  • options: An object specifying cleaning options:
    • removeDuplicates (Boolean): Remove duplicate entries (default: false).
    • fillMissing (Any): Fill missing values with the specified value.
• Returns: An array of cleaned objects.
• Example:

  const cleanedData = cleanData(data, { removeDuplicates: true, fillMissing: 0 });

3. analyzeData(data: Object[]): Object

• Description: Performs statistical analysis on the given data.
• Parameters:
  • data: An array of objects to analyze.
• Returns: An object containing analysis results such as averages and totals.
• Example:

  const results = analyzeData(cleanedData);

4. plotData(data: Object): void

• Description: Generates a visualization based on the analysis results.
• Parameters:
  • data: The analysis results to visualize.
• Returns: None. The function renders the plot.
• Example:

  plotData(results);

🛠️ Additional Features

• Error Handling: All functions include basic error handling to manage issues like file not found or invalid data formats.
• Support for Multiple File Formats: While primarily focused on CSV, you can extend parsing to support other formats with additional functions.
• Customization Options: Many functions accept additional parameters to customize their behavior (e.g., specifying which columns to analyze).
