i need to create one online webapp
Budget: $10 – $30 AUD
Here's a textual description of the flow for your online app to plot Point and Figure charts:
1. **Start Application:**
- User launches the web application.
2. **Render HTML Form:**
- The application renders an HTML form with dropdowns for selecting symbols and expiry.
3. **User Selects Symbol and Expiry:**
- The user selects a symbol and expiry from the dropdown lists.
4. **User Clicks "Plot" Button:**
- The user clicks the "Plot" button to initiate the chart plotting process.
5. **Capture Selected Symbol and Expiry:**
- JavaScript captures the selected symbol and expiry from the form.
6. **Send AJAX Request to Flask Backend:**
- JavaScript sends an AJAX request to a Flask backend API endpoint, passing the selected symbol and expiry.
7. **Flask Fetches Data:**
- Flask receives the AJAX request and fetches chart data from a database or an external API based on the selected symbol and expiry.
8. **Process Data and Generate Chart:**
- Flask processes the fetched data and generates the Point and Figure chart.
- The chart can be generated using a charting library like Plotly, Chart.js, D3.js, etc.
9. **Render Chart on Frontend:**
- The processed chart data is sent back to the frontend.
10. **Display Chart to User:**
- The frontend renders and displays the Point and Figure chart to the user.
11. **End Application:**
- The user interacts with the displayed chart and may choose to end the application.
This flow provides a step-by-step sequence from the start of the application to the display of the Point and Figure chart based on the user's symbol and expiry selections. Adapt the steps and incorporate specific implementations based on your chosen technologies and requirements.
