Step 2: ⌨️ Coding

• Modify src/Visualization.php ✓ 9a2699f Edit

Modify src/Visualization.php with contents:
• Add a new parameter `$format` to the `plot_chromosomes` function to allow specifying the output format (PNG or SVG).
• Inside the `plot_chromosomes` function, add a conditional block to handle SVG generation. Use PHP's XMLWriter or similar functionality to create SVG elements based on the chromosome data. This involves iterating over the `$collections` array and creating SVG rectangles (``) for each range.
• For the CSV generation, add a new function `generate_csv` that takes `$matchedData` and a file path as parameters. Use PHP's built-in `fputcsv` function to write the matching data to the specified CSV file. This function should be called at the end of the `plot_chromosomes` function if CSV output is requested.
• Ensure that the color allocation and image creation logic currently in place for GD is appropriately adapted for SVG output, including converting color values to a suitable format for SVG.

Modify src/MatchKits.php with contents:
• Modify the `visualizeMatchedData` method to accept an additional parameter for the output format, which should be passed through to the `plot_chromosomes` function in `Visualization.php`.
• Update the method call to `plot_chromosomes` within `visualizeMatchedData` to include this new parameter, allowing the user to specify their desired output format.

• Create src/Helpers/CSVGenerator.php ✓ 037a6f5 Edit

Create src/Helpers/CSVGenerator.php with contents:
• Create a new PHP class `CSVGenerator` in the `src/Helpers` directory. This class should have a public static method `generate` that accepts an array of matching data and a file path as parameters.
• Inside the `generate` method, open a file handle for the specified path and use a loop in combination with `fputcsv` to write each item of the matching data array to the CSV file.
• Ensure proper error handling for file operations, such as checking if the file is writable and handling file opening failures.
• This class can then be used in `src/Visualization.php` for generating CSV files as part of the visualization process.

• Modify src/Visualization.php ✓ 0665716 Edit

Modify src/Visualization.php with contents:
• Import the newly created `CSVGenerator` class at the top of the `Visualization.php` file.
• In the `plot_chromosomes` function, after generating the image (PNG/JPEG) or SVG, call `CSVGenerator::generate` with the `$matchedData` and a specified file path for the CSV output. This integrates CSV generation into the visualization process.
