Draw from a single point to ten points that fall into a single line. Also draw dots on the end points.

A complete bipartite graph is a graph with two sets of vertices where there is no edge between vertices belonging to the same set; but all vertices of different sets are fully connected. Draw the K(10,10) where each set have 10 vertices.
In a previous project we draw real stock price charts by reading data from files. We also draw stock moving averages in this project. Download historical stock prices for Google, Apple, and SPY and draw 20-day and 50-day moving averages for the last 1000 trading days.

Refer to fully connected octagon before drawing this fully connected 24-gon.
Use nested for loop and list to draw the following fully connected octagon.
Draw a regular hexagon that have vertices connected to the center. Use for loop to draw this shape.

Download historical stock prices for Google, Apple, and SPY. Read the file and draw the stock charts for these companies. The following figures show the stock prices for these companies:

Moving averages can smooth out the stock prices and reduce the randomness. Based on the previous projects (stock price random walk with candlestick chart, and trending stock price random walk with candlestick chart), add 10 day and 25 day moving averages to the charts.
In a previous project, we draw a trending stock price random walk chart. Candlestick chart is a more common way of representing stock price chart. Modify the code for the previous project to draw stock price random walk with Candlestick Chart.
