A online tool that helps students to make complex graph by just entering an equation & find the line of best fit fit

line-of-best-fit is utility tool for mathematicians and physicist which helps students to Plot points in a graph and automatically plots the line of best fit. Furthermore it helps to draw graphs using multiple formats of equations.

• Plots points on graph and additionally draws the line of best fit.
• Draws graphs for equations in following formats:
  • Linear Equation: y = mx + c
  • Complex Function Equation: f(x)
  • Implicit Equation: f(x, y) = 0
• User Friendly Interface:
  • Plotly graphs make it more accessible for feature like: zooming, paning, scalling and more
• Savable graphs: User can download the graph as a (.png) file

• Python 3.13+ (I used 3.13.5 but anything 3.13+ should work fine)
• pip for installing packages
• flask 2.0 or greator
• Any modern browser (Chrome, Firefox, Edge the simulations use Canvas API)

1. Clone the repo:

   git clone https://github.com/sujalnegi/line-of-best-fit.git
   
   cd line-of-best-fit

2. Create a virtual environment (recommended):

   Makes a seprate environment for the repo

   Windows:

   python -m venv venv
   ..\venv\Scripts\activate

   macOS / Linux:

   python3 -m venv venv
   
   source venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

4. Run the app:

   python app.py

5. Open it up:

   Go to http://127.0.0.1:5000 in your browser

1. The home page has the plotting and best fit line function.
2. Then the user can navigate through navigation bar.
3. The graphs of function and linear equation can be made by the "Graphs" feature
4. The graphs of [f(x, y) = 0] can be made with the "Complex Graphs" feature
5. There is a download button for graphs through which user can download the current graph
