Reference no: EM132854229

Task: Use Vega-Lite to create visualisations that answer the following analysis questions:

- Describe trends and anomalies with respect to chemical contamination in the Boonsong Lekagul waterways.
- Describe any data quality and uncertain issues, such as missing data, change in collection frequency, and unrealistic values (e.g. water temperature higher than 100 degrees).
- Describe any particular concern for the Pipit or other wildlife.

Requirements:

o There should be at least one Vega-lite visualisation for each analysis question. Usually, 2-3 visualisations (including dashboard) is expected for each questions.
o The number of visualisation depends on the number of findings in the answer: for example if three patterns are found for Question 1, one or more visualisations are expected for each pattern.
o Besides the visualisations, the answer to each question should include text that describes and discusses:
o What the finding is (a pattern, an anomaly, etc.);
o How the finding can be seen from the visualisation;
o How the visualisation design supports the analysis, i.e. what the data and analysis task are and how the visualisation is designed to match and support them.
o Any advanced Vega-lite visualisation features used, such as multi-layer, chart concatenation, and interaction.
o Any additional (non-visual) analysis used and how it contributed to the answer.
