+* Overview of =daily-totals.py= Script
+
+I have assumed you have ran ~./separator.sh~ and ~./totalilator.sh~, created a
+virtual-environment (venv) (~python3 -m venv venv~) and installed the dependencies
+(via ~pip -r install requirements.txt~). See the project's [[file:../README.org][README]] for more
+information on setting the repository up.
+
+#+begin_src shell
+  cd <PATH TO RITHERDON-CHARTS>
+  # Activate the virtual-environment if you haven't...
+  source venv/bin/activate
+
+  # Run the script...
+  python daily-totals.py

+
+* Design/Trade-Off Notes and Decisions
+
+1. The data used with this script is the most /symmetrical/, for lack of a
+   better word, of all the CSV files I worked with. The number of rows and
+   values in the ~date~ column (in both CSV files) are the same. So, there was
+   no mapping issues along the x-axis -- like other scripts/charts.
+2. I plotted the data on the chart with lines because that is the type of chart
+   Nicola wants the main data/charts to be presented in.
+   1. The aims of this script is a secondary pursuit. I did not think too much
+      about the overall goal of it. The main aim of the project is/was to
+      produce some line charts, so that is were my thinking is/was. This script
+      is just a continuation of working in that vain. There is no reason for
+      sticking with using a line chart with this script.

+* What the Script Does
+
+Essentially, it takes the total number of reading recorded for each day, for
+each Light Meter, and plots them on the chart. For example, it will show on
+~2021-06-15~ (16^th June 2021) Light Meter 1 recorded ~59336~ readings and Light
+Meter 2 recorded ~117487~. It does this for every day and each line on the chart
+represent one Light Meter.
+
+Below is a sample of the data used by this script -- taken from
+=../data/light-meter-1-daily-totals.csv=,
+
+|               date | reading |
+|--------------------+---------|
+|         2021-06-13 |       6 |
+|         2021-06-14 |   86729 |
+|         2021-06-15 |       0 |
+|         2021-06-16 |   59336 |
+| MORE READINGS HERE |     ... |

+|         2021-07-30 |   49776 |
+
+The ~date~ column is used for the x-axis and the ~reading~ column is used for the
+y-axis.
